Extracardiac total cavopulmonary connection using a Y-shaped graft.

We report on 17-year-old Fontan candidate with a severely distorted central pulmonary artery (PA) who underwent a successful extracardiac total cavopulmonary connection using a Y-shaped bifurcated graft. A nonanatomic pathway from the inferior vena cava to the left PA was constructed and positioned anterior to the ascending aorta. The other arm was used as a conduit between the inferior vena cava and the right PA. All procedures were performed under temporary venous bypass without cardiopulmonary bypass.
