A technique for right heart bypass using autogenous lungs for oxygenation was evaluated. Venous blood was collected by a catheter placed in the right atrium and caudal vena cava. The blood then passed through the extracorporeal unit and was pumped into the pulmonary circulation. This technique allowed direct surgical exposure of the conus arteriosus, pulmonary valve, and pulmonary trunk. The surgical procedure, plasma hemoglobin levels, platelet and leukocyte counts, arterial blood gas, serum proteins, electrocardiogram, and postmortem findings were evaluated. Although there were significant alterations in many of these parameters, seven of eight dogs were successfully perfused and recovered rapidly from the surgery. One dog died of complications arising from inadequate venous return before bypass was established. On the first postoperative day, the survivors were ambulatory, eating, and having normal bowel function. Right heart bypass may be an effective method to approach lesions involving the conus arteriosus, pulmonary valve, and pulmonary trunk.
