Rare Mechanical Complication of Percutaneous PFO Closure Leading to Recurrent Strokes in a Teenage Boy

Abstract

An 18-year-old male subject presented with recurrent strokes 3 years after percutaneous patent foramen ovale (PFO) closure with an PFO occluder device for presumed PFO-related stroke. A transesophageal echocardiogram revealed apparent device displacement during dynamic cardiac cycle. This case highlights an unusual but important delayed complication of transcatheter PFO closure.
