Timing for successful surgical management of heart block after placement of an Amplatzer occlusion device for secundum atrial septal defect repair.

摘要

Atrioventricular (AV) blocks are rare complication that can occur after device closure of an atrial septal defect (ASD).1'2 Review of the manufacturer and user facility device experience (MAUDE) database by Delaney, Li, and Rhodes3 indicated one reported complication of a second-degree AV block after insertion of an ASD occlusion device. Development of complete AV block is even less common.4 Most of these cases resolve either spontaneously or with medical management in a few days. We report a case in which complete AV block did not resolve spontaneously and was successfully treated by surgical explantation of the device and patch closure of the ASD.
