    “It adds to the growing body of evidence that a PFO has multiple, potentially adverse, consequences that are often not noticed. Although a plethora of literature addresses stroke in patients with a PFO, no systematic study has evaluated embolism in other organ systems,” he wrote. “[This study] also encourages the introduction of better imaging to detect currently unidentified pathology.”

    Another stroke survivor/PFO story 

    This is the original article from Readers’s Digest Race Against Time that I referenced in my PFO story. The archive was down for some time but here once again is the entire article. Well worth the read as it goes over new technology now available to repair / remove damage from stroke, but you have to recognize stroke symptoms and act fast to get help ASAP.

    __________________________________________________

    Traci Miller woke up to the sound of quick footsteps scampering toward her room. It was shortly before dawn on a rainy Saturday in April 2006, but her three-year-old daughter, Alexis, was up unusually early. Traci tucked the toddler back in bed, then checked on one-year-old Rylee, who was sound asleep in her crib. It would be nice to slide under the covers for a few more minutes. But the redheaded mom from Hacketstown, New Jersey, had a busy day planned. She and her husband, Michael, had an appointment with a real estate agent to look at larger houses for their growing family, and her parents would be visiting later in the day. “I’m going to take a shower,” she told Michael, who was still dozing. “I’ve stuff to do before Mom and Dad get here — and we need groceries too.”

    Seconds later, Michael heard a thud. He didn’t know it, but a desperate race against time had just begun. He leapt out of bed to see what was wrong. In the bathroom, he found his wife of five years slumped against the tub. “I was screaming her name and asking if she was okay, but she just stared straight ahead and didn’t answer,” says the 36-year-old civil engineer. “She was moaning, kind of crying. I was terrified.” He carried her to their bed, then dialed 911. During the call, he noticed that Traci couldn’t move her right leg. “That scared me even more.”

    Within minutes, police rushed in with their radios blaring. Since Traci couldn’t talk, they asked Michael what had happened. “Maybe she hit her head and got a concussion,” he replied. Before long, the bedroom was full of paramedics, who examined Traci, slipped a brace around her neck, and loaded her onto a stretcher. During the wait for the ambulance, which was delayed on another call, Michael asked a neighbor to come over and watch the kids until he could reach relatives. Amazingly, baby Rylee slept through the commotion, and Alexis played quietly in bed, unaware of the emergency.

    By the time the ambulance finally arrived, Michael was frantic. The right side of Traci’s face had developed an alarming droop, and her mouth hung open. She was raced to a local hospital, then airlifted to a trauma center in Morristown, New Jersey. “I knew they wouldn’t do that unless her condition was very serious,” says Michael, who followed in his car. “I was crying as I drove. How could she have hurt herself so badly slipping in the bathroom? I panicked to the point that I thought about losing my wife, and our girls growing up without their mother.”

    When Michael reached Morristown Memorial Hospital at 7:40 a.m., he tried to get his emotions under control. During a brief visit with Traci, who was paralyzed on the right side of her body, he discovered that she could communicate with head motions. “Did you fall?” he asked. She nodded yes. “Do you remember how you fell?” She shook her head no. Then she was wheeled off for tests, including a CAT scan, while Michael prayed in the waiting room and called home to check on the kids.

    Nearly an hour later, ER doctors returned with shocking news: Traci had suffered a stroke — loss of blood flow to part of the brain, usually caused when a vessel is blocked by a clot. Michael couldn’t believe it. How could this have happened? His wife, a slim, physically fit nonsmoker, was only 35. His mind raced from one terrifying scenario to another. One of his relatives had a stroke and was never the same afterward. Would that happen to Traci? Would she ever walk or talk again? Was she going to die? Strokes kill more than 157,000 Americans a year, about 60 percent of them women. Survivors can be left with paralysis, impaired vision, chronic pain, difficulty speaking, or cognitive or emotional problems.

    The neurologist explained that it might be possible to reverse the stroke. But it all depended on whether Traci could be treated in time. The longer her brain went without blood flow, the greater the damage. Before the doctors could do anything, they needed to pinpoint when the symptoms started. There are only two FDA-approved therapies for stroke, and both had to be given within strict time limits. Michael hadn’t looked at a clock, but his best guess was that she was stricken at around 6 a.m., or possibly a little later.

    Sparing Death With the Merci Retriever

    The specialist checked his watch. It was 8:45 a.m. There were just minutes left to administer tPA (tissue plasminogen activator), a clot-busting drug that’s only approved for use within three hours of a stroke. But the doctor worried that the clot in Traci’s brain was too big to dissolve with tPA. If it didn’t work, she’d be left profoundly disabled, if she survived at all. Up to 50 percent of people with a blockage where Traci’s was die.

    Traci also qualified for a newer procedure, then offered at only one facility in her state: Overlook Hospital, in Summit, New Jersey. A corkscrew-like device called the Merci Retriever (FDA approved in August 2004) is designed to pluck clots out of blocked vessels like corks from wine bottles. It’s more beneficial than tPA for large blockages and works for up to eight hours after a stroke, says Ronald Benitez, MD, Overlook’s director of endovascular neurosurgery. “Expanding the treatment window means many more patients will be spared death or disability, since most people don’t get to the hospital in time for tPA.”

    The Merci treatment has serious risks, including punctured blood vessels (brain hemorrhaging), which could worsen the stroke or even be fatal. And since the hospital had recently acquired the device, Traci would be only the second patient in New Jersey to undergo the procedure, which is 54 to 69 percent effective at restoring blood flow, according to a 2006 study at University of California, San Francisco. Faced with a life-or-death decision, and a ticking clock, Michael didn’t hesitate. Scrawling his signature on a consent form, he shouted, “What are you waiting for? Let’s get her moved to the other hospital!”

    While doctors scrambled to make the arrangements, Michael called Traci’s parents. “I hoped I’d made the right decision,” he says. “I would have agreed to anything if it gave Traci a better chance at getting back to normal. She didn’t seem to be suffering, but when the doctor asked her to stick out her tongue, she couldn’t even do that.” Michael sped to Overlook Hospital so fast that he actually beat the ambulance there. When Traci arrived, about 10 a.m., he kissed her and promised that the surgeons would help her. “I must have said ‘I love you’ a hundred times before they pulled me away. I was bawling my head off.”

    Four and a half hours after the stroke began, Traci was put under general anesthesia. Dr. Benitez threaded a tiny tube into an artery in her leg. Using x-ray images as a digital road map, he navigated through a maze of blood vessels to her brain. When he reached the blocked vessel, he squirted tPA directly into the clot, a still experimental use of the drug. “That loosens the clot up so it’s easier to extract,” the surgeon explains. The next step was inserting the Merci Retriever into the tube. The Retriever is a flexible wire made of metals that have “memory.” When the nickel and titanium tip comes out the other end of the tube, it “remembers” to curl into a corkscrew. If all goes well, it snares the blockage when pulled back through it.

    But Dr. Benitez’s first attempt only captured a few fragments — just enough to start a trickle of blood through the obstructed vessel, like water spilling from a leaky dam. Not good enough. The process was carefully repeated. “Traci’s being so young and having two kids added to the urgency,” Dr. Benitez says. The device was slowly extracted. To the doctor’s relief, a huge clot was tangled in its coils. X-rays showed blood surging through the vessel at the normal rate. Two much smaller vessels, though, were still clogged. Dr. Benitez squirted in more tPA and they slowly regained flow, except in one tiny area. He’d done all he could to bring her back.

    Soon after the 90-minute procedure, Traci could wiggle her right leg. When she saw Michael in the recovery room, around 1 p.m., her first words were, “I love you.” He was amazed and ecstatic. It seemed like a miracle that she could speak so soon after the procedure. She was moved to the neurology ICU, where several anxious relatives were waiting to see her. A nurse explained after such a severe stroke, they’d have to monitor Traci’s progress one day at a time. It was too soon to predict whether she’d regain all of her former abilities, even with extensive rehabilitation. Michael sat at his wife’s bedside, holding her hand. “You’re going to be just fine,” he promised. “You’re a fighter and can overcome this.” Traci nodded slowly, then drifted off to sleep.

    Bringing Back Traci

    Over the next 24 hours, he rejoiced at each new milestone. Although her speech was soft and slurred, she whispered simple words, such as “yes,” “no” and “hi.” She also recognized friends and relatives who dropped by, and even greeted her brother-in-law by his nickname, “Dupe.” On Sunday afternoon, a day and a half after the stroke, she took her first steps, with the aid of a walker. “I was very excited, relieved and hopeful,” says Michael. Even though Traci seemed dazed, and had limited use of her right arm, he was convinced that over time, she’d recover 100 percent.

    The next day, however, there was a setback. When a doctor checked her vision, she didn’t react when he shone a flashlight into her left eye. “I was devastated that I couldn’t see on that side,” says Traci, who was struggling to understand what had happened to her. “I didn’t get the whole stroke thing, or why something was wrong with my left eye, when the other problems were on the right side of my body.” The doctor thought that a fragment of the clot might have blocked flow to a vessel in that eye during the stroke, but he held out hope that her vision might eventually return. By the end of the week, she could see shadows.

    She graduated from a walker to a cane, and began to speak in complete sentences. “I’m going to be okay,” she told her parents. They were helping Michael care for the kids. Rylee was too young to talk, but Alexis kept asking to see her mom. She had to wait until Traci was moved from the ICU to a regular hospital room. Before the visit, Michael explained that Traci used Play-Doh to exercise her hand. Alexis rifled through her toy box until she found a container of pink Play-Doh, the little girl’s favorite color. “This will help Mommy get better,” she proclaimed. Traci was so happy to see the children that she burst into tears, then put Alexis in her lap while they squeezed and molded the Play-Doh together.

    After a week, Traci was transferred to a rehabilitation center, where she received physical, occupational and speech therapies. Two weeks after the stroke, she was well enough to go home and begin outpatient treatment. Before long, she was walking without a cane, though her right foot dragged, causing her to stumble frequently. She gradually learned to walk normally, and her right arm gained greater strength and flexibility, though it remains weaker than the left. Learning to write again was a struggle. At first, she could barely print her name, but eventually, her penmanship was nearly perfect.

    As her physical skills returned, her thinking also got sharper. “About four weeks after the stroke, it finally hit me how serious this was. I wanted to know, Why me?” Tests revealed a previously undiagnosed birth defect: a small hole in her heart that made her more prone to stroke. However, doctors decided to postpone repair until she was further along with her recovery. Meanwhile, sight gradually returned to her left eye, though her vision is blurry on that side. She fumbles for a word occasionally but has no other speech problems.

    In early July, she returned to her job at a pharmaceutical company. “I’m amazed that I had a 50-50 chance of dying, but I’m still here,” says Traci, who had a cardiac repair operation in September. She’s also had an emotional change of heart. “I’ve cut back on my hours at work, and I take more vacations. My life is here at home with my girls and my husband, and I want to enjoy it to the fullest.”

    We need to do more 

    I know this is a start but we need to do more to raise stroke awareness. I was contacted on my blog today by AGA Medical letting me know of their new stroke awareness campaign. Congratulations, this is a step in the right direction, but it is something we should have started years ago. Here’s what they wrote,
    “Thanks for your work on stroke awareness with Tedy’s Team. I know you are familiar with AGA Medical Corporation.
    We have just launched a new stroke awareness campaign called TacklingStroke on Twitter, Facebook, and YouTube. It features video testimonials from professional football player Tedy Bruschi, who had a stroke in 2005, recovered fully, and was able to resume his career.”

    The post references a video link to Tedy’s PR piece about the stroke warning signs, but the FDA still prohibits AGA Medical from mentioning the word PFO. Here’s the video, it is the same one that has been on AGA’s site except now you view it on YouTube:
    http://www.youtube.com/user/TacklingStroke

    Bottom Line:
    We need to do more by getting out there and educating in our schools, so our teachers, coaches and youth know stroke warning signs. Tonight I’m at Lincoln Middle School doing just that. If you think I did A good job, post your comments here. If you think I can improve, I want to know more. If you want to help with my goals, I’ll take that too!!

    Drop me a line, I don’t bite….

    Treadmill train to promote brain gain 

    Treadmill-Training Benefits Stroke Patients

    Treadmill-training has been making headlines recently in stroke therapy treatment.  From the fitness standpoint, we have known for some time that studies have shown that people get more out of a treadmill than other fitness equipment because it is natural to walk or run, and users are more apt to stick with it for longer each session.  This article will review a recent study using treadmills in stroke rehabilitation, as well as at some of the latest treadmill products on the market today.

    Image Preview

    The Research

    According to recent research at Johns Hopkins University School of Medicine, Baltimore, people who use treadmill-training can significantly improve their health and mobility.  The results of this study, validated through brain imaging, that brain changes reflected actual neural “rewiring” -even years after having a stroke.

    The study’s results, published in Stroke, the journal of the American Heart Association, suggest that patients’ brains may retain the capacity to rewire through a treadmill exercise program months or years after conventional physical therapy has ended.1

    Bloggers abuzz about sex and stroke 

    WOW!- I know, I used the word sex and “the other “s” word” together- I can explain…

    I mentioned in my last post I’d be following up with more information on the emerging technologies available to enhance stroke rehabilitation outcomes. Well, this post as you can tell from the title is not about stroke rehab directly, (although many stroke survivors might argue that sex would be the most enjoyable and welcomed component to any therapy plan of care).

    Anyway, my point in including this post here is that it confirms my suspicion when you add those three little letters together to form the word “sex” it certainly pulls readers in to any headline and grabs attention.

    The proof: I’ve never seen more bloggers post on any one single stroke related topic in a given week, than this past one, EVER.

    Here’s only a few of the recent headlines:

    “Holy ^@#~ ! “ A stroke from Sex
    35yr Old Woman has Orgasm Related Stroke
    When Sex Leads To Stroke

    That’s enough- I think you get my point….

    Image PreviewUnfortunately, the rise in attention recently for stroke awareness came at the expense of a 35-year old Illinois woman. She, too, at the time probably didn’t realize that sex with her boyfriend could trigger a life threatening stroke that temporarily left one side of her face numb, slurred speech and weakness in her left arm. While her physician treated her, it is reported he was puzzled to find that his patient did not “fit the profile of a typical stroke sufferer”. This stroke survivor is a young, healthy, non-smoking woman with no known cardiovascular risk factors.

    Her doctor acted FAST…

    Her physician found it too late to inject her with tPA, a clot-busting drug that must be administered within three hours of a stroke. In what was reported as a risky decision, he ran a catheter from an artery in the groin to her brain, applying tPA directly to the clot. Her symptoms improved almost immediately and within an hour she was out of danger and is reported to be well on her way to a full recovery.

    Why did I add my first post on sex and stroke?

    Well, I can assure you it was not to grab headlines, Sarah Palin is still leading that category these days. This unfortunate incident did remind me of a topic that wasn’t discussed much during the management of my PFO or during my own stroke rehab. Yes, sex. Is it safe when you have a PFO or other similar known heart defect?

    So, to get to the answer (maybe) let’s look at what was the reason for the recent headline grabbing “stroke after sex” which perpetuated a blogging frenzy As a rule, sex and orgasm triggered strokes are rare in young men and women, though not unheard of. For such a stroke to occur in a relatively young person, experts still argue that it perhaps requires a combination of factors and events, not unusual in themselves, but extremely unlikely to occur at the same time. One variable that seems to be consistent in the cases that have been reported involving young people who (were brave enough to tell the truth) had suffered similar sex related strokes, is that they all had a small opening in the wall between the two upper chambers of the heart, as was in the case of this young Illinois woman. This minor heart defect or opening, called Patent Foramen Ovale (PFO), as you can read more about throughout my blog, is found by many reports to be seen as frequently as in one in four adults. Such an opening allows some blood to flow from the right to the left side of the heart, bypassing lungs only to go straight to the brain. As there are no symptoms, most people with PFO do not know they have this heart defect. It has been reported that 40% of people suffering a cryptogenic stroke ( i.e.) a stroke with no known cause, have been found to have PFO.

    Is sex the culprit?

    It is well reported that strain can cause increased blood flow through a PFO. For example, the strain of bearing down during a bowel movement, strain of breathing out of a shut mouth or holding a breath, and strain during sex, particularly during orgasm,. Experts will mostly agree strokes are not caused by PFO’s alone, there must be a small blood clot present, which must break free and enter the heart, then cross over and bypass the body’s normal “pulmonary filter” instead traveling through the PFO then up to the brain. Normally, the rule of thumb is that small blood clots stuck in the lungs dissolve, but a blood clot that passes through a PFO lodges itself in the brain and causes a stroke.

    Again, with the Illinois woman serving as our own case study here, this young patient suffered a headline grabbing “sex-related stroke” because of her PFO. It was also reported she had a small blood clot in her leg, the possible side effect of oral contraceptives taken for birth control. Doctors generally still report that a vast majority of people with PFOs, often go through life without any problems, and while the risk of stroke during sex must be kept in perspective, the risk is low if you consider the chain of events needed and presented in this post. Fortunately, according to stroke experts, sexual intercourse, in itself, is not likely to trigger a stroke without accompanying risk factors.

    So, now l can get back to writing and researching for my next post of emerging stroke technologies and hope to have that available soon. In the meantime, please use the recent sex and stroke buzz to be reminded that strokes occur all year long, just not during Stroke Awareness Month in May. In fact, here are the stats:

    • 700,000 Americans suffer a stroke each year
    • Approximately 160,000 die of stroke each year

    The most common risk factors for stroke in young people are those linked to migraines, drug use, coagulation diseases, or athletic injuries that cause trauma or injury in the blood vessels, especially in the neck. Even with these risk factors, the chances of a young person suffering from stroke are extremely small but that is no reason to be ignorant of the warning signs. As I’ve been saying all along, there are young faces of stroke and you should know what they look like. Be prepared and get help fast. Know-Stroke!

    As one stroke campaign says well, Time Lost is Brain Lost

    Until next time-

    Do you know-stroke? 

    Know-Stroke

    May is Stroke Awareness month:

    Do you know-stroke?

    May 1,2008

    Acknowledging the month of May as “Stroke Awareness Month” offers advocates for stroke awareness, stroke survivors and their families and caregivers an opportunity to educate the public about the devastating and debilitating effects of stroke. I offer this page on my sites today exactly one year to the day that I had heart surgery to repair a PFO that caused my stroke. Last year I woke up from surgery and still was not sure what the future held as far as being able to return to work and family responsibilities. I did realize, however, that on May 1st I was given a new beginning. Today, I give thanks to all who helped in my recovery, from all the great staff at MGH and especially to my wife, my real stroke hero for helping me keep the faith and constantly encouraging me on my “journey”.

    For more on my story and how I am determined to raise stroke awareness please visit my blog at know-stroke.org

    I posted this page especially today so that you may Know-Stroke and Be Stroke Smart by:

    • Reducing Stroke Risk
    • Recognize Stroke Symptoms
    • Responding FAST by calling 911

      What is stroke?
      A stroke occurs when a blood clot blocks a blood vessel or artery, or when a blood vessel breaks, interrupting blood flow to an area of the brain. When a stroke occurs, it kills brain cells in the immediate area.2 types of stroke:

      Ischemic strokes can occur two ways and are the most common, accounting for 84% of strokes.
      Hemorrhagic stroke is a second type of stroke which occurs when a blood vessel in the brain breaks or ruptures. While these stroke are less common, they are more deadly.


      Brain Attack


      The term “Brain Attack” gives stroke the most descriptive, realistic and powerful call to action. A brain attack should warrant the same degree of seriousness and emergency care as a heart attack. After all, your brain is your body’s most vital and delicate organ.Immediate response is crucial because every minute lost, from the onset of symptoms to the time of emergency contact, cuts into the limited window of opportunity for intervention.

      CALL 911 for immediate assistance.
      Treatment is available and is most effective if administered within the first three hours of experiencing symptoms.
      Your chances of walking out of the hospital with little to no disability are improved by 30 percent if you receive t-PA, the only FDA-approved stroke treatment available.

      Know these stroke facts:

    • Stroke is a leading cause of adult disability. Over the course of a lifetime, four out of every five American families will be touched by stroke.
    • There are ways to reduce your risk for stroke- (see below)
    • Every 45 seconds someone suffers a stroke, every 3 minutes someone dies from a stroke.
    • Twice as many women die from stroke every year than from breast cancer.

    The most common stroke symptoms are:


    • Sudden numbness or weakness of face, arm or leg, especially on one side of the body
    • Sudden confusion, trouble speaking or understanding
    • Sudden trouble seeing in one or both eyes
    • Sudden trouble walking, dizziness, loss of balance or coordination
    • Sudden severe headache with no known cause

    If you see someone having these symptoms or experience any of these symptoms yourself, call 911 immediately. Treatment can be more effective if given quickly. Every minute counts.

    Common misperceptions of stroke…

    Stroke is not preventable
    Stroke cannot be treated
    Stroke only strikes the elderly
    Stroke recovery ends after the event/initial trauma to the brain

    Realities of stroke are:
    Stroke is largely preventable.
    Stroke requires emergency treatment. Call 911 immediately if you experience or see someone with stroke symptoms.
    Anyone of any age can have a stroke.
    Stroke is a “Brain Attack”
    Stroke recovery can continue throughout life.


    Stroke Prevention Guidelines:


    1. Know your blood pressure. Have it checked at least annually. If it’s elevated, work with your doctor to keep it under control. Having high blood pressure, or hypertension, increases stroke risk four to six times.2. Find out if you have atrial fibrillation – a type or irregular heartbeat. If left untreated, AF can increase stroke risk four to six times.

    3. If you smoke, stop. Smoking doubles stroke risk.

    4. If you drink alcohol, do so in moderation. Recent studies have suggested that modest alcohol consumption (up to two glasses of wine or alcohol equivalent) may reduce stroke risk.

    5. Find out if you have high cholesterol. High cholesterol can indirectly increase stroke risk by putting people at greater risk of heart disease.

    6. If you’re diabetic, follow your doctor’s recommendation carefully to control your diabetes. People with diabetes have a higher stroke risk. This may be due to circulation problems that diabetes can cause.

    7. Include exercise in the activities you enjoy in your daily routine. Active people tend to have lower cholesterol levels. Regular exercise also seems to slow down or stop the clogging of blood vessels by deposits.

    8. Enjoy a lower sodium (salt), lower fat diet. Too much salt may contribute to high blood pressure and make it more difficult to control. A diet that’s low in fat will likely include vegetables, lean meats such as chicken and fish, low-fat dairy products and a limited number of eggs.

    9. Ask your doctor if you have circulation problems which increase your risk for stroke.

    10. If you experience any stroke symptoms, seek immediate medical attention. CALL 911! Every minute counts!

    Patent Foramen Ovale

    Your septum

    • The septum is the muscular wall separating the heart into the left and right sides.
    • The atrial septum is the wall separating the atria (the two upper chambers).
    • The ventricular septum is the wall separating the ventricles (the two lower chambers).

    Patent Foramen Ovale (PFO)

    The foramen ovale is a small hole located in atrial septum that is used during fetal circulation to speed up the travel of blood through the heart. When in the womb,a baby does not use it’s own lungs for oxygen-rich blood, it relies on the mother to provide oxygen rich blood from the placenta through the umbilical cord to the fetus. Therefore, blood can travel from the veins to the right side of the baby’s heart and cross to the left side of the heart through the foramen ovale and skip the trip to the baby’s lungs.

    Normally the foramen ovale closes at birth when increased blood pressure on the left side of the heart forces the opening to close.

    If the atrial septum does not close properly, it is called a patent foramen ovale. This type of defect generally works like a flap valve, only opening during certain conditions when there is more pressure inside the chest. This increased pressure occurs when people strain while having a bowel movement, cough, or sneeze.

    If the pressure is great enough, blood may travel from the right atrium to the left atrium. If there is a clot or particles in the blood traveling in the right side of the heart, it can cross the PFO, enter the left atrium, and travel out of the heart and to the brain (causing a stroke) or into a coronary artery (causing a heart attack).

    How Common is Patent Foramen Ovale?

    The prevalence of PFO is about 25 percent in the general population. In patients who have stroke of unknown cause (cryptogenic stroke), the prevalence of PFO increases to about 40 percent. This is especially true in patients who have had a stroke at age less than 55 years. (http://stroke.ahajournals.org/cgi/content/full/37/2/577)

    A PFO can be associated with atrial septal aneurysm, which is characterized by excessive mobility of the atrial septum.

    Symptoms of PFO

    Most patients do not have any symptoms with PFO.

    Stroke and PFO: About 40 percent of patients who have an ischemic stroke have no known cause (called cryptogenic stroke). PFO is present and associated with an increase in stroke in about 40 percent of cases. The most common symptoms of stroke are:

    • weakness or numbness of the face, arm or leg on one side of the body
    • loss of vision or dimming (like a curtain falling) in one or both eyes
    • loss of speech, difficulty talking or understanding what others are saying
      sudden, severe headache with no known cause
    • loss of balance, unstable walking, usually combined with another symptom

    Migraine headache and PFO: Migraine headaches are more common in patients with PFO. While it seems as though closure of PFO results in improvement of migraine symptoms, larger studies are needed to confirm this finding.

    Diagnosis of PFO

    Patent Foramen Ovale can be detected by echocardiogram. In some cases the patient is asked to cough or perform the Valsalva maneuver to increase pressure in the right atrium. This can increase the flow of blood from the right to left atrium. Transesophageal echo, can provide a closer and more detailed view of the PFO.

    Treatment for Patent Foramen Ovale (PFO)

    Medical management

    People with PFO do not need any treatment if there is no associated problems, such as a stroke. Patients who have had a stroke or transient ischemic attack (TIA) may be placed on some type of blood thinner medication, such as aspirin, plavix (clopidogrel), or coumadin (warfarin) to prevent recurrent stroke.

    Non-surgical treatment: Cardiac implant

    In some patients a cardiologist and a neurologist may reccomend closure of PFO. Most frequently, percutaneous rather than surgical closure is preferred. As part of the procedure, you will first undergo a cardiac catheterization. During this test, catheters (hollow, flexible, tube) will be inserted into the veins in your groins and advanced to your heart. A balloon may be placed across the opening to determine the size and location of the hole in your heart. Measurements are taken of the pressure inside your heart chambers. A tiny catheter with an echo transducer is placed in the heart for imaging.

    If the cardiac catheterization shows your PFO is an appropriate size and in an appropriate location for closure with this device, the cardiologist will position the device to close the hole.

    Two closure devices

    Currently there are no specially designed devices for PFO closure that is approved by the FDA. In patients that closure is indicated, devices that are approved for other heart defects are used.

    The CardioSEAL® device is a small double umbrella arms attached to Dacron fabric. It is folded into a special catheter, similar to the catheter used during your catheterization. The special catheter is inserted into a vein in the leg and advanced into the heart and through the hole. The device is slowly pushed out of the special catheter allowing each umbrella to open up and cover each side of the hole (like a sandwich) and close it. When the device is in proper position, it is released from the special catheter. Over time, heart tissue grows over the implant, becoming part of the heart.

      I went swimming two weeks post op. I forgot to take medication beforehand and naturally experienced increased elevated heart rate. I stopped as soon as I realized. Is there any chance of rupture. Any advice, please?

      Steve;
      Two weeks post op is way too early to be pushing your luck with going swimming (in my opinion). Even more than getting your heart elevated too fast so soon after PFO closure, you are doing an activity that forces you to hold your breath and increases pressure. Slow it down and let that thing heal,PLEASE. Getting it out of your ticker, if it moves before your body had firmly embedded it in the septum, is a major possibly(open heart) procedure and not worth the risk.

      I had a cardioSEAL pfo device placed in 2007. I recently had a chest injury which I think resulted in a fractured sternum/xiphoid process. I Had xrays today, still awaiting the report. I, however, saw an xray done 4 days after the injury and the lateral view of the sternum showed a perfect butterfly as it would look ready to fly away with round wings outstretched and 2 antennas. I received info that it should look like a single butterfly at rest, with overlying wings. The radiologist said in his report that it was some kind of closure device, “overlying” the heart, and didn’t mention it was any where near the pfo closure, and no mention of the device still closing the hole. I had a echocardiogram and a bubble study on Friday, and the dr. says it is still in place, should look like a spider, no problem, and no bubbles went to the wrong side. Do you think it possible that 1/2 of the device is loose and moved? My other NP called and said another dr looked at previous xrays, and the current one and says it is still the same place.( I should say that on Mon I was vomiting blood, and the next day had to go to the ER due to a BP of 198/130 and 9/10 pain in my stomach), But there was no overlying pattern, just a single outline of 1 pair perfect butterfly wings. I have had worse uncontrolled BP’s since the injury, major upper stomach pain just under the sternum/xiphoid process area, and no one seems to think it possible that could move and it is perfect. I wonder what happened. What do you think?

    A Hole in the Heart-Good PFO Tipsheet by stroke.org 

    Patent Foramen Ovale (PFO) and Stroke

    Line General

    Source: stroke.org and AMA Medical
    Have you had a stroke or TIA (transient ischemic attack or mini-stroke) “out of the blue” with no obvious risk factors? Did doctors check to see if the stroke or TIA may have been caused by a “hole” in the heart called a patent foramen ovale (PFO)? About one in five Americans has a PFO. Many don’t know it until a medical condition like a stroke or TIA occurs. PFOs often have no symptoms but they may increase your risk for stroke and TIA. Many PFO-related strokes are called cryptogenic, meaning they have no apparent cause.
    What is a PFO?
    Line General
    All people are born with flap-like openings in their hearts. But, for most, the opening closes by itself shortly after birth.
    In some people, an open flap remains between the two upper chambers of the heart (the left and right atria). This opening can allow a blood clot from one part of the body to travel through the flap and up to the brain, causing a stroke.
    What can you do about it?
    Line General
    The first step is to get a diagnosis. An ultrasound of the heart, called an echocardiogram, can show doctors if a PFO is present.
    The second step is to ask your doctor about treatment options. Currently, there are two main treatment methods for PFO: medicines or PFO closure, which can include open-heart surgery or a newer procedure that closes the flap without major surgery.
    The medicines don’t treat the actual PFO. They can control clotting factors in the blood so stroke-causing blood clots are less likely to form in the first place.
    Open-heart surgery is rarely used for people who don’t respond to the drugs. But, as with any major surgery, patients and their doctors need to weigh the risks of the surgery with the benefits before moving ahead with this treatment option. In recent years, a new approach has been developed enabling doctors to seal the PFO without major surgery. An implanted closure device, which can resemble a tiny two-ended umbrella, is delivered to the PFO using a small tube threaded to the heart from a vein in the thigh. The implant is inserted through the flap and released from the tube. It expands and tissue grows in and around the implant to seal the PFO from both sides. This procedure requires minimal recovery time. Currently, the U.S. Food and Drug Administration (FDA) allows this treatment method only for “humanitarian” uses, meaning that the procedure is only used for people who don’t respond to the medicines and have already had a second stroke.
    On-going Research
    Line General
    Which is the better treatment option: medicine or PFO closure? That question still needs to be answered.
    The good news is that research now is being conducted to see if PFO-closure implant procedures are better than medications at helping reduce the risk of recurrent stroke in stroke and TIA survivors. But, the only way scientists will have meaningful research studies is if they have enough people participating.
    If you or someone you know has had a PFO-related stroke or TIA and is interested in learning more about treatment options for the PFO through a clinical trial, you can get more information about clinical trials by calling 1-800-STROKES (800-787-6537) or by visiting the Clinical Trials Resource Center.
    As a participant in a clinical trial, you are carefully evaluated by doctors and receive extensive follow-up care. During your treatment, you may also receive the latest version of a current PFO closure device. The FDA has approved a prior version of this device and more than 15,000 people around the world have been treated with this procedure. You will also be helping medical science find the most effective treatment to lower the number of PFO-related strokes and TIAs

    Tags: , oprah moment, PFO, , , Tesy Bruschi renews contract with Patriots   

    A reply to Tedy Bruschi’s “Never Give Up” book 

    I sent this letter off back in August of 2007.  I’ve been inspired by the recent phone calls and posts that have come in with stories all too similar to mine. Because of these stories, I’m going to begin to fill in the gaps of my stroke story and timeine with the purpose of helping others paint a clear picture of what still needs to be done to improve awareness with cryptogenic stroke.  That begins with a personal letter I had filed away that I had sent off to Tedy and Heidi Bruschi after reading the book “Never Give Up”.  I was reminded of the letter after hearing in the news yesterday that Tedy has renewed his contract with the New England Patriots-which by the way, is great news for New England.  I hope he also finds time to renew his efforts with spreading the word about fighting stroke.  Anyway, here’s what I am referring to:

    Originally written 6 August 2007

     

    Dear Tedy and Heidi;

     

    I just finished reading Never Give Up and I felt compelled to send a note off to you both.  I clearly admit I was one of those doubters you referred to in your book.  Having three small children of my own, I could not even consider why you would risk returning to play football in the NFL.  I know now how blind I was to what you and Heidi had gone through. Unfortunately, I learned first hand this life lesson and then later it was reinforced by reading your book.

     

    You see, in the Fall of 2006, I had a stroke at age 39 from the same cause, a PFO that was never detected at birth.  I feel like I am just now on the same journey back home as I write this note.  In many ways, even though I had my PFO closed on May 1, 2007  and have worked through most of the physical limitations from the stroke, I am still going through much of the emotional recovery you described so well. 

     

    I admit I was angry with you for quite some time Tedy.  I know, you’re thinking you don’t even know me, so it is unfair for me to make that statement.   When doctors finally found out what had caused my stroke, I was reaching out for help to find answers.  No one could help me sort through what decision my wife and I needed to make to get me healthy again.   The real reason I said I was angry with you was that I was so desperate to speak with someone who had come out on the other side after the PFO procedure and returned to their regular life and you were the only “young face” of stroke I knew of.  I sent emails to you through the Pats website, left messages by phone at Gillette Stadium all to no replies.  I am no longer angry after reading your story, and realize your position and the energy it took to recover.  It was not even that I expected a personal reply, it was more that I was thinking here is a guy that the world knows and loves and he is being silent about this at a time when he could be making an enormous impact in stroke awareness.  I could not have been more wrong. My sincere apologies.

     

    Part of my educational journey to get some answers led me to meeting Zach Blackburn through the ASA American Stroke Association) and your organization.  I am so glad I went up to Framingham to meet him personally.  I shared both my enthusiasm and frustration with him during our meeting.  At the time I was still awaiting a decision before the PFO committee at MGH and I was in a mental state where I needed to put things back “in my own hands”.  I spelled out my frustration with Zack about not having enough resources for young stroke survivors and the lack of education/knowledge for PFO’s and especially that related to the brain/heart connection.  I wanted to make some changes and I brought up a copy of my own story (which I had written out of frustration) to him. He probably feels I was all hype at my convictions to get national attention for this component of needed stroke education, but I promise to you I am only more dedicated to this cause now, after closure, than at the time of that meeting back in March.  (I’ve included a copy of my story if you would like to learn more.)  I am sure Zack dismissed my enthusiasm and placed this article on his desk, but I plan to speak to him more on this topic at our next Tedy’s Team event this weekend.

     

     

    As you’ll learn if you skip through the PFO background information, and go to what I call my “Oprah moment”  – this is where our stories go off course and it is this part of my story that I need to see to a better end for future stroke survivors.

     

    I could relate to the trips back and forth to MGH, all the testing, even getting mad at the doctors up there at times (I had more then one angry moment with Dr. Palacios), and I even was laughing at the description of your stomach from the heparin injections post-op because my midsection looked just the same.  While there were so many similarities to my own situation and I owed the same “thank you’s” to many of the same doctors and support staff at MGH after my procedure, I also experienced a much different approach to getting to the decision to close my PFO.  If you read my story, you’ll learn more, but the short of it is so much more attention to this topic is needed.  I know you must realize you both are in a position to impact so many lives in a positive way and that is why I hope you are planning now for your own “Oprah moment” to take your important message nationally.

     

    My biased judgment of your book is that there will undoubtedly need to be a “part 2” because it is that good.  I expect you’ll be flooded with stories like my own and would need to follow-up with the impact your book will present.  I believe, as does most every person in New England, you both have a powerful message to get out there and perhaps the book is just the beginning.  

     

    In closing, after meeting several of Tedy’s Team members for the first time last week in Marlboro, it is clear I am on the right team to help you both get this job done.  I also had the opportunity to be introduced to a real genuine stroke hero when I met you, Heidi, briefly that evening.  I know that I would not be standing today without the support of my own hero, my wife Lisa.  Tedy, you describe there are two faces of stroke, young and old.  I think there is also a third face and it is the face of the real stroke heroes, the person(s) you lean on for support when you are going through this process-the caregivers and loved ones who step up and keep you strong.    Quite honestly, I was feeling a bit overwhelmed last week when I thought of the tasks that lie ahead.  I was getting puzzled by how to create the “Oprah moment” this stroke education campaign needs in the media to raise awareness. Your book, along with a reminder from my stroke hero Lisa, came at just the right time and has me back on track focused on what needs to be accomplished. 

     

    Please let me know if there is anything I can do to help you both get to that “Oprah moment”.  In the meantime please keep quarterbacking this cause and I’ll continue to do my part on your team.  

     

    Best of health,
