Legacy Heart Center: Some Migraines May Start in the Heart.A Cardiac Procedure for Stroke Prevention May Cure Migraines as Well PLANO, Texas Plano (IPA: /ˈpleɪnoʊ/) is a wealthy suburb of Dallas, Texas, located to the north, mainly within Collin County, but also extending into Denton County. According to the 2000 U.S. -- A cardiac procedure that has been used to help patients avoid repeated life-threatening strokes may turn out to be a cure for some acute migraine sufferers as well. The procedure, which is called a patent foramen ovale patent foramen ovale PFO Cardiology An opening between the left and right atria which allows blood to bypass the lungs in utero; the FO normally closes shortly after birth, but remains open in up to 20%; a PFO is, in absence of other cardiac defects, is of no consequence (PFO PFO Patent Foramen Ovale (defect of the heart) PFO Paphos, Cyprus - International (Airport Code) PFO Principal Federal Official (US Departement of Homeland Security) ) closure, involves sealing off a flap-like opening between the upper two chambers of the heart that in three out of four people normally closes on its own within a year after birth. "For most people with PFO, the condition causes no problem and goes untreated," explained Srini Potluri, M.D., a cardiologist Cardiologist Doctor who specializes in diagnosing and treating heart diseases. Mentioned in: Electrophysiology Study of the Heart, Lithotripsy cardiologist a physician who specializes in the diagnosis and treatment of heart disease. at Legacy Heart Center who has successfully conducted the procedure on some 70 patients. "But for some, the PFO is thought to cause strokes and closing the PFO has helped to substantially reduce subsequent strokes," he added. "Serendipitously, the procedure has also been shown to help some migraine sufferers." PFO closure is a non-surgical procedure in which a catheter is inserted into a blood vessel blood vessel n. An elastic tubular channel, such as an artery, a vein, a sinus, or a capillary, through which the blood circulates. blood vessel(s), n the network of muscular tubes that carry blood. in the groin area and guided to the heart where an umbrella-like device is placed over the PFO. Although there is no clinical proof that PFO closure works for migraine sufferers, several studies have shown a possible link between PFOs and migraines and several doctors--including Dr. Potluri--have reported that closing a PFO in patients with migraine headaches Migraine Headache Definition Migraine is a type of headache marked by severe head pain lasting several hours or more. Description Migraine is an intense and often debilitating type of headache. and a previous stroke has reduced the frequency and intensity of migraines. Dr. Potluri noted that it is not clear why patients with a PFO would be more likely to have migraines, or how a PFO closure works to reduce them, but, he says, "I have seen direct evidence that it helps stroke victims and migraine sufferers. In fact several of the procedures I have performed were done exclusively to help migraine sufferers. These patients were in such severe pain that their neurologists referred them to me to perform the PFO closure and it worked." Dr. Potluri cited a study that was completed in England last year called MIST (Migraine Intervention with STARFlex[R] Technology) study, a double-blind study double-blind study, n experimental technique in clinical research in which neither the researcher nor the patient knows whether the treatment administered is considered inactive (placebo) or active (medicinal). designed to evaluate the effect of PFO closure on migraines. The study showed that the procedure may be an effective way to treat certain types of migraines. A MIST II study is underway in the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. and scheduled to be completed by the end of this year. In addition to MIST II, there are several other PFO/migraine studies underway, Dr. Potluri noted. Until the research studies are completed sometime next year, the procedure remains "off-label" or not approved for curing migraines, Dr. Potluri noted and should only be performed in extreme circumstances. For now, he recommends that patients who suffer from migraines and are interested in the procedure contact Legacy Heart Center for a referral to one of the ongoing trials. Dr. Potluri specializes in carotid stenting Carotid stenting (CAS) is a minimally-invasive surgical procedure available to correct carotid stenosis (narrowing of the carotid artery lumen by atheroma). Carotid stenosis can present with no symptoms (diagnosed incidentally) or through symptoms such as transient ischemic attacks and is one of Legacy Heart Center's 15 cardiologists and more than 100 other health and administrative professionals.
