A Very Late Life-Threatening Complication After Percutaneous Closure of an Atrial Septal Defect.

Percutaneous closure is widely recognized as the first therapeutic option in the majority of cases of secundum atrial septal defect (ASD) because of its high effectiveness and safety. Nonetheless, with the progressive increase of implanted devices and follow-up duration, several adverse events, some of them potentially life-threatening, have been reported. We report the case of an asymptomatic aortic erosion that occurred 13 years after the procedure. The main feature of our case is the very late occurrence of a life-threatening asymptomatic complication of ASD percutaneous closure, which should prompt lifelong surveillance in this population.
