Conversion of atriopulmonary to cavopulmonary anastomosis in management of late arrhythmias and atrial thrombosis

Ann Thorac Surg. 1994 Nov;58(5):1510-4. doi: 10.1016/0003-4975(94)91945-3.


The original atriopulmonary connection or "classic" Fontan operation is associated with several late complications such as arrhythmias, right atrial dilatation, and thromboembolism. This report describes our experience with 3 patients who presented with the acute onset of atrial arrhythmias and upon further evaluation were found to have significant hemodynamic lesions. After failing medical management, all 3 patients were treated successfully with surgical conversion of their atriopulmonary connection to a lateral tunnel cavopulmonary Fontan. The postoperative course of these patients was uneventful. However, long-term evaluation is needed to assess the efficacy of this technique in the prevention of postoperative morbidity.
