Long-term results of atrial maze surgery in patients with congenital heart disease

166 patients with congenital heart disease undergoing cardiac surgical procedures (137 with preoperative atrial arrhythmias [therapeutic group], 29 at high risk for post-operative arrhythmias [prophylactic group]). Most common lesions were single ventricle (27% in therapeutic) and Ebstein's anomaly (76% in prophylactic).

Maze procedure (right atrial 63%, left atrial 4%, bilateral 33%) performed concomitantly with cardiac surgical procedures.
