Abstract:
Anomalous origin of the pulmonary artery from the ascending aorta can lead to congestive heart failure in infancy, and with advancing age many patients will experience severe pulmonary hypertension. Surgical intervention has high mortality and morbidity risks if this happens. Strategies to manage these patients seem only limited to heart-lung transplantation or lung transplantation. Here, we successfully performed surgical intervention in an adult patient who had anomalous origin of the right pulmonary artery from the ascending aorta with high pressures in the ascending aorta and normally originating pulmonary artery.
