Patent foramen ovale (PFO) closure reduced the risk for recurrent ischemic stroke in most young and middle-aged adults with cryptogenic stroke but increased the risk for atrial fibrillation (AF) in a ...

New research shows that cryoablation is a safe and effective approach to close congenital patent foramen ovale (PFO, a small hole in the heart) in patients with atrial fibrillation (AF) undergoing ...

We postulated that cryoablation can also fuse PFO by injuring the primary and secondary septum." Although AF and PFO are both risk factors for stroke/TIA, it is difficult to determine whether PFO is ...

Whether closure of a patent foramen ovale reduces the risk of recurrence of ischemic stroke in patients who have had a cryptogenic ischemic stroke is unknown. In a multicenter, randomized, open-label ...

Current age-based restrictions on patent foramen ovale (PFO) closure should be reconsidered in light of observational data suggesting that carefully selected older patients fare as well as those who ...

CHICAGO, Nov 15 (Reuters) - NMT Medical Inc's catheter system that seals a hole in the heart worked no better than drugs to prevent stroke in a study, suggesting physicians perform too many closure ...

As a baby develops in the womb, a hole in its heart provides oxygen-rich blood from the mother. This hole usually closes naturally when the baby is born. However, about 25 percent of the time, it does ...
