Abstract
Atrial fibrillation (AF) is the most commonly treated arrhythmia in clinical practice and is often found in association with an atrial septal defect (ASD). However, ASD closure rarely confers complete arrhythmia control. A 23-year-old man presented to our center with frequent episodes ofpalpitations. AF was documented in 12-lead electrocardiography, and echocardiography showed a secundum-type ASD, 14 mm in size, with a significant left-to-right shunt. ASD closure was performed successfully with an ASD occluder device with no residual shunting. During follow-up, the patient experienced several episodes of AF. Thirteen months after the ASD closure, cryoballoon pulmonary vein isolation was done successfully with no complications. During a 12-month follow-up, he had no symptoms or AF recurrences, and echocardiography showed no residual shunting. This study showed that cryoballoon pulmonary vein isolation could be performed successfully without residual shunts in patients with ASD closure devices. [ABSTRACT FROM AUTHOR]
