Amplatzer septal occluder and atrioventricular block: A case report and literature review

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.
