Aortic sinus-left atrial fistula after interventional closure of atrial septal defect.

A 3-year-old boy underwent interventional closure of an atrial septal defect using an Amplatzer septal occluder. After 4 weeks, an aortic sinus-to-left atrial fistula was detected by echocardiography in an asymptomatic child. The device was surgically explanted with fistula and atrial septal defect closure. Follow-up was uneventful. Copyright 2005 Wiley-Liss, Inc.
