Concomitant Intraoperative Radiofrequency and Microwave Ablation of Atrial Fibrillation and Repair of Atrial Septal Defect

Atrial fibrillation (AF) is the most frequent form of atrial arrhythmias in adults with congenital heart disease. Some serious complications are related with the presence of AF after surgery. Because of the complexity and the risk of bleeding, the Maze III procedure has been largely replaced by alternative energy sources. A patient with multiple atrial septal defects (ASD) and AF underwent surgical closure with autologous pericardial patch and radiofrequency and microwave ablation of AF
