Delayed perforation of a transcatheter patent foramen ovale occluder 10 years after implantation.

To date, closure of a patent foramen ovale (PFO) by the transcatheter technique is the preferred method, and an operation with cardiopulmonary bypass is reserved for special indications. Although different closure devices are used with high efficacy, adverse events after transcatheter PFO closure have been reported. We describe an unusual case of a cardiac perforation occurring 10 years after transcatheter PFO closure. The device was explanted surgically, and the interatrial communication was closed with a polytetrafluoroethylene patch.
