The Efficacy of Pulmonary Vein Isolation for Two Cases of Persistent Atrial Fibllilation with Atrial Septal Defect

Aim: Pulmonary Vein Isolation (PVI) has been performed for cure non-valviler atrial fibllilation (AF) cases. It is not clear the effect of PVI for AF with congenital heart disease. We studied the efficacy of PVI for two cases of persistent AF with atrial septal defect (ASD) Case 1: 62 y.o. male. He had pointed arrhythmia, and consulted the hospital because of dyspnea. He had been diagnosed ASD and persistent AF. LVEF was 30%. AF was converted to sinus rhythm under Amiodarone. After PVI, Paroxysmal AF (PAF) was observed, but sinus rhythm was maintained without Amiodarone and LV systoric function improved to normal. He will undergo catheter ASD closing operation after second PVI. Case 2: 52 y.o. female. She had been diagnosed ASD and PAF. She was admitted because of CHF with persistent AF and hyperthyroidism. Persistent AF was converted to sinus rhythm by electrical defibrillation under Beprijil at euthyroidism. After first PVI AF recurrence was not observed, but LA-PV conductions ware maintained at second PVI. After second PVI AF recurrence was not observed with Bepridil. She will undergo catheter ASD closing operation. Conclusions: PVI for AF with ASD were seems to be good procedure before catheter ASD closing operation.
