Patent Foramen Ovale Morphology and Impact on Percutaneous Device Closure

We sought to evaluate the effects of atrial septal and patent foramen ovale (PFO) morphology on the efficacy of transcatheter closure. We performed a retrospective analysis of all patients who underwent PFO device closure from January 1997 to January 2002. Forty-seven patients underwent percutaneous closure of a PFO with a median age of 45 years (range, 8–75) and weight of 76 kg (range 28–115). The septal morphology was flat in 33 and aneurysmal...
