Comparison of Effect of Combined Intravenous Amiodarone and Surgical Closure of OS ASD in Adults with Surgical Closure alone on Sinus Conversion of Concomitant Atrial Fibrillation — A Retrospective Case Series Analysis

ABSTRACT

Closure of Atrial Septal Defect has been proposed to increase conversion of concomitant Atrial Fibrillation (AF) to Normal Sinus Rhythm (NSR). Amiodarone is known to convert AF to NSR. Our findings support the use of single intraoperative dose of intravenous Amiodarone for increased conversion of pre-operative AF to NSR in OS ASD patients undergoing closure on CPB, although the effect was short lasting
