Abstract

Transcatheter device closure of atrial septal defects is now considered an alternative option to open heart surgery with good short-term and long-term results (Du et al., J Am Coll Cardiol 2002;39:1836-1844, Chessa et al., J Am Coll Cardiol 2002;39:1061-1065); in comparison with surgical closure, the complication rate is lower (Du et al., J Am Coll Cardiol 2002;39:1836-1844). Arrhythmias are known infrequent complications of device closure. However, complete heart block is a rare complication of both treatment modalities (Chessa et al., J Am Coll Cardiol 2002;39:1061-1065). We report two patients who developed atrioventricular (AV) block within 48 hr after uncomplicated device closure of ASD using the Amplatzer septal occluder (ASO) device. Despite trials of high dose steroids and non-steroidal anti-inflammatory agents in both patients, the response was inadequate and by the end of the first week, both patients were ultimately sent for surgical removal of their devices with complete resolution of their atrioventricular conduction abnormalities. We discuss the possible etiology and risk factors of AV block and propose recommendations for management of such a complication.
