Abstract:
Transcatheter closure of secondum atrial septal defect (ASD) is an alternative option to open heart surgery with good short and long-term outcomes. For this purpose, the Amplatzer septal occluder (ASO) device is widely used. Arrhythmias are known complications of ASD device closure including atrial ectopy and heart block. We report a seven-year-old female patient who developed second degree atrioventricular block (AVB) within few hours after ASD device closure using ASO device. At the seventh post-procedure day; while under close observation; patient regained sinus rhythm which was maintained thereafter. A 3-day course of prednisolone was given.
