Operative treatment of truncus arteriosus communis coexisting with tricuspid atresia

The coexistence of tricuspid atresia and common arterial trunk is extremely rare. We present a successful three-stage surgical treatment of this defect. The first stage included disconnection of the pulmonary arteries from the common trunk, atrial septectomy and systemic-to-pulmonary shunt; the second stage, a hemi-Fontan procedure; and the third stage, a fenestrated Fontan completion. The child is now 8 years old and is developing well. (C) 2000 by The Society of Thoracic Surgeons.
