Abstract

Transcatheter closure of atrial septal defect (ASD) is the most common approach to close the defects worldwide. In this approach, persistent conduction disturbance is extremely rare, but an acute increase in supraventricular ectopy and minimal risk of atrioventricular conduction disturbance, as complete heart block, has been seen. Here, we report a patient who underwent ASD closure with device and presented with persistent complete heart block 10 days after device occlusion due to inflammatory tissue formation just near the atrioventricular node area at the floor of the right atrium without any direct compression on the triangle of Koch.
