Protruding umbrella into the left atrium associated with recurrence of a stroke: a possible late complication of the CardioSEAL occluder.

Percutaneous closure of a patent foramen ovale or atrial septal defect using various closure systems is now considered an alternative to surgical therapy in selected patients with cryptogenic strokes. We report the case of a late protrusion of the umbrella of a CardioSEAL Occluder into the left atrium associated with occurrence of a stroke. No recurrence of symptoms was seen at six-month follow-up after reinstitution of clopidogrel in addition to aspirin.
