Failure of devices used for closure of atrial septal defects: mechanisms and management

J Thorac Cardiovasc Surg. 1996 Jul;112(1):21-6. doi: 10.1016/s0022-5223(96)70173-3.


Various devices for transcatheter ASD closure are undergoing clinical trials. Each new device claims advantages in terms of safety and efficacy over earlier devices. We report three cases in which a new investigational device--the Das angel wings--failed. Emergency operations were necessary for device retrieval and defect closure. The possible mechanisms of the event and the options in management are discussed with a review of literature on all devices.
