Prevention of Right Pulmonary Artery Stenosis in Fontan Circulation: The Melbourne Modification of T-Fontan Operation

Abstract

Currently, the extracardiac Fontan operation is a procedure of choice in patients undergoing a staged palliation for univentricular hearts. However, it is not always easy to prevent the right pulmonary artery twisting after implantation of the extracardiac conduit. Herein, we described a simple modification, which we referred to as T-Fontan procedure, to prevent right pulmonary artery stenosis after extracardiac Fontan operation.
