An operation achieved success in correcting the truncus arteriosus anomaly. The pulmonary arteries were disconnected from the truncus, and, by the manner in which the ventricular septal defect was closed, it became the true aorta. A new outflow from the right ventricle to the pulmonary arteries was established by the use of a homograft of ascending aorta including the aortic valve. This use of a homograft may be the factor that allowed success in the operation as opposed to previous attempts at similar operations with synthetic materials. The corrective operation will probably prove to be the method of choice for the treatment of patients with truncus arteriosus.
