Aortic valve leaflet entrapment by a percutaneous closure device.

Abstract

Iatrogenic aortic valve leaflet perforation and aorto-right atrial fistula are rare adverse events of transcatheter interventions and transseptal radiofrequency ablations, respectively. We present the case of a 62-year-old man who experienced acute, severe aortic insufficiency as a result of leaflet entrapment by a septal occluder device during attempted percutaneous closure of an iatrogenic aorto-right atrial fistula. This rare adverse event emphasizes the need for a thorough understanding of cardiac anatomy to minimize transcatheter adverse events and to recognize and treat them appropriately when they occur.
