title: Reconstruction of right ventricular-pulmonary artery continuity with a valved external conduit: unusual technical considerations.
abstract: The Hancock conduit containing a porcine xenograft valve has been used as part of the repair in 14 patients having complex congenital heart disease. The single death in this series resulted from the consequences of pulmonary vascular disease in a patient with truncus arteriosus. Several unusual technical considerations such as previous pulmonary artery banding, angulated Waterston anastomoses, and dextroversion required modifications in the standard approach to the correction of several of the anomalies encountered. This conduit has provided a satisfactory method to establish right ventricular-pulmonary artery continuity.
