title: Tetralogy of Fallot with anomalous coronary artery: double outflow technique.
abstract: A new technique to repair tetralogy of Fallot with an anomalous coronary artery crossing the right ventricular outflow tract is described, together with intermediate term follow-up. Using a pedicled flap of the anterior pulmonary artery wall as the floor, and a vascular or prosthetic patch as the roof, a composite conduit with the potential for growth is constructed. Together with the native outflow tract, this provides unobstructed egress from the right ventricle to the branch pulmonary arteries. Since 1990, 4 infants aged 2-weeks to 6-months have undergone primary repair using this technique. Intermediate term follow-up shows adequate durability of the repair.
