TheFetus.net - Premature closure of the foramen ovale -Jose M. Sierra, MD. Philippe Jeanty, MD, PhD. Eleni Tzachrista, MD It is well known that the foramen ovale is the shortcut through which the fetal heart provides oxygenated blood to preferential organs, mainly the brain and the heart itself. Pericardial effusion, right heart enlargement with left bulging of the septal walls and absent foramen ovale’s flap with left bulging are well described ultrasonographic findings in late premature closures of the foramen ovale. Premature closure of the foramen ovale as a cause of intrauterine fetal ascites. www.thefetus.net /page.php?id=891

Transcatheter Closure of Patent Foramen Ovale (PFO) "Transcatheter closure of the patent foramen ovale allows us to prevent further neurological damage from recurrent strokes in these patients without resorting to open heart surgery or lifetime treatment with blood thinners", says Lawrence Ong, MD, Director of Interventional Cardiology at North Shore university Hospital in Manhasset. Studies have shown an increased risk of stroke in patients with a patent foramen ovale despite the use of blood thinner medication.  Stroke from a PFO tends to occur in younger patients, sometimes even teenagers. The procedure involves having a cardiac angiogram to visualize the heart and the extent of the PFO.  A catheter is advanced from a small incision in your groin to your heart. www.northshorelij.com /body.cfm?id=2846   (422 words)

My Patent Foramen Ovale PFO (Patent foramen ovale) is a persistent opening in the wall of the heart which did not close completely after birth (opening required before birth for transfer of oxygenated blood via the umbilical cord). Furthermore, a widely patent foramen (>5mm separation) and a severe shunt (< 50% of the left atrium filled with contrast) have been identified as echocardiographic predictors of an increased risk for paradoxical embolism in a recent retrospective study. This opening can cause a shunt of blood from right to left, but more often there is a movement of blood from the left side of the heart (high pressure) to the right side of the heart (low pressure). www.geocities.com /safhireohio/ovale.html   (422 words)

Foramen Ovale Patent A patent foramen ovale (PFO) is a hole between the upper chambers (or atria) of the heart. An ASD is a persistent hole in the heart wall (septum) while a patent foramen ovale (PFO) is a potential hole that acts like a check valve, only opening when the pressures between the venous side of...

Patent Foramen Ovale Closure The Foramen Ovale is an opening between the upper chambers of the heart called the right and left atria. A PFO is something like a flap valve between the upper chambers of the heart that usually remains closed and functions normally. During this procedure agitated saline is inserted into the upper right chamber of the heart and using echocardiography a physician can determine if the bubbles are passing directly into the left atria. www.ihimontana.org /cardiology-patent-foramen-ovale-closure.php   (514 words)

YMCA Scuba Currents Articles Foramen Ovale is an anatomical structure in the fetal heart, which plays an integral role in the fetal circulation. Now that we have a grasp of what Foramen Ovale is and its role in fetal circulation, the next question is what is a PFO in the adult human heart? Although the Foramen Ovale is still open, increased pressure in the left atrium is sufficient to limit blood flow from the right to the left atrium. www.ymcascuba.org /ymcascub/currnt14.html   (514 words)

Foramen ovale - Wikipedia, the free encyclopedia In the fetal heart the foramen ovale allows blood to enter the left atrium of the heart from the right atrium. Normally this opening closes in the first year of life, however in about 30% of adults a small patent foramen ovale is still present. At the base of the skull the foramen ovale is a hole that transmits the mandibular nerve, the en.wikipedia.org /wiki/Foramen_ovale   (514 words)

DAN Divers Alert Network : Patent Foramen Ovale The foramen ovale is an opening, or communication, between the right atrium and left atrium in the heart. Recently, there has been interest in the anatomic variant of normal in the human heart: It is termed patent foramen ovale (PFO - pronounced PAY-tent fore-A-men O-val-eh), and through research, DAN is exploring its possible importance for scuba divers. (Foramen is Latin for opening, or aperture; ovale is, appropriately, Latin for oval, indicating the shape of the aperture.) The normal passage of blood in the adult human is from the great veins of the body, through the right atrium into the right ventricle, and then via the pulmonary artery to the lungs. www.diversalertnetwork.org /medical/articles/article.asp?articleid=50   (514 words)

HeartCenterOnline For Patients - Diameter of a patent foramen ovale is a risk factor for ischemic events A patent foramen ovale is a naturally occurring blood channel in the prenatal heart that fails to close after birth. Nov 9 (Reuters Health) - The diameter of a patent foramen ovale (a hole in the heart) is an independent risk factor for ischemic events, especially recurrent strokes, Dr. Herwig W. Schuchlenz, of LKH- Universitatsklinikum Graz, Austria, and colleagues report in the October 15th issue of The American Journal of Medicine. The team reports that the mean diameter of a patent foramen ovale was significantly larger in patients than in controls, at 4 mm and 2 mm, respectively. www.heartcenteronline.com /myheartdr/home/research-detail.cfm?reutersid=383   (514 words)

Patent Foramen Ovale (PFO) Patent Foramen Ovale (PFO) is a developmental abnormality of the wall separating the top two chambers of the heart.

Interventional procedure consultation document - percutaneous closure of patent foramen ovale for the prevention of cerebral embolic stroke A patent foramen ovale is the persistence of a hole (the foramen ovale) in the wall (septum) between the right atrium and left atrium of the heart. Treatment options include medical treatment with antiplatelet (eg aspirin) or anticoagulation therapy, surgical closure (open-heart surgery), and percutaneous closure of the patent foramen ovale. The National Institute for Clinical Excellence is examining percutaneous closure of patent foramen ovale for the prevention of cerebral embolic stroke and will publish guidance on its safety and efficacy to the NHS in England, Wales and Scotland. www.nice.org.uk /nws.asp?o=222147&u=41881&p=/IP237consultation   (514 words)

Lars Erickson - Patent Foramen Ovale (PFO) A patent foramen ovale (PFO) is a type of atrial septal defect ( ASD), or opening between the two upper chambers of the heart (left and right atria). In some individuals the patent foramen ovale may be larger than usual, and this can result in some of the problems that accompany other types of atrial septal defects (see ASDs). This risk of this complication is very tiny in most people, and is not felt to outweigh the risk of surgical or catheter-directed closure of a patent foramen ovale in the vast majority of cases. www.larserickson.com /PatientInfo/ASD_PFO.htm   (514 words)

Percutaneous closure of the patent foramen ovale for the prevention of cerebral embolic stroke A patent foramen ovale is the persistence of a hole (the foramen ovale) in the wall (septum) between the right atrium and left atrium of the heart. Treatment options include medical treatment with antiplatelet (eg aspirin) or anticoagulation therapy, surgical closure (open-heart surgery), and percutaneous closure of the patent foramen ovale. The foramen ovale usually closes spontaneously after birth; however, in as many as 1 out of 4 people, the foramen ovale does not close completely and it remains patent throughout life. www.nice.org.uk /page.aspx?o=90648   (319 words)

Stroke, PFOs (patent foramen ovale), and returning to "normal" A patent foramen ovale (PFO) is a hole between the upper chambers (or atria) of the heart. The front-running candidate is a small hole in my heart- a PFO - which by rotten luck, may have allowed a clot to pass from the "safe" venous side, into the arterial side, with a fast track to the brain. For example, the average PICSS participant age was 59; of the PFO group, 60% had hypertension, 49% were obese, 28% were diabetic, 29% were smokers, 12% were heavy drinkers, and 35% were sedentary. users.viawest.net /~hwstock/stroke/stroke_main_hws.htm   (4360 words)

Patent foramen ovale At birth, with the development of the pulmonary circulation, the pressures are reversed and the increased pressure in the left atrium forces the septum primum to close the foramen ovale. In a substantial number of persons, the foramen ovale stays patent throughout life. The foramen ovale is a natural interatrial channel, delimited inferiorly by the thinner flap-like septum primum and superiorly by the thicker septum secundum (Jeanrenaud & Kappenberger 1991, Movsowitz herkules.oulu.fi /isbn9514267435/html/x239.html   (4360 words)

AllRefer Health - Medical News > Migraines can be cured by a heart operation: Study The heart defect is known as patent foramen ovale (PFO). The researchers said that after patients had a procedure to close a "hole-in-the-heart", some reported that their migraines had disappeared or had been reduced in severity or frequency, reports The telegraph. After people got a PFO closure to treat decompression sickness, those who suffered migraine reported that attacks had stopped. health.allrefer.com /news/index.php?ID=7149   (4360 words)

Congenital Heart Disease: Septal Defects 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. 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. If the atrial septum does not close properly, it is called a patent foramen ovale. www.clevelandclinic.org /heartcenter/pub/guide/disease/congenital/pfo.htm   (4360 words)

Medical Encyclopedia: Patent foramen ovale (Print Version) The foramen ovale normally closes soon after the infant is born. PFO is the persistence of a fetal opening between the left and right atria (upper chambers) of the heart. If PFO is present, the clot can then pass from the right side to the left side from whence it can travel to the brain and become lodged there, preventing blood flow to that part of the brain (stroke). www.nlm.nih.gov /medlineplus/print/ency/article/001113.htm   (466 words)

Congenital Heart Disease: Septal Defects 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. 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 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. www.clevelandclinic.org /heartcenter/pub/guide/disease/congenital/pfo.htm   (1200 words)

Patent Foramen Ovale Patent Foramen Ovale is not a disease, but only a remains of the anatomy of the heart before birth (picture). Before being born, the lungs have no function in oxygenating the blood (because the fetus is immersed in water), and all the oxygen is transported via the umbilical blood vessels, from the placenta. The reason for this is twofold: Firstly, DCS is caused by nitrogen bubbles, not by the PFO by itself. www.daneurope.org /eng/cadintro.htm   (1271 words)

Barnes-Jewish Hospital - Patent Foramen Ovale (PFO) A patent foramen ovale, or PFO, is an opening between the upper two chambers of the heart that have failed to close after birth. Patients with known strokes and a PFO are frightened and concerned because they are usually young, seemingly healthy individuals with no other diseases present. PFOs are increasingly being suspected as the cause of paradoxical embolic events. www.barnesjewish.org /groups?NavID=1323   (809 words)
