The early morbidity and mortality of the Ross Procedure was attributed mainly to hemorrhage and to problems in harvesting the pulmonary autograft or implanting the pulmonary homograft. Arrhythmias were attributed to injury to the first septal perforator. Since the very early experience of Dr. Ross1 there have been remarkably few reports of similar problems with this area.We will concentrate of four areas: the anatomy of the right ventricular outflow tract, aortic/pulmonary valve relationships, coronary artery anatomy in normal hearts, and coronary artery anatomy in hearts with aortic stenosis. To this end, 45 autopsy specimens were examined at the Children's Hospital of Pittsburgh: 20 normal hearts being compared with 25 from patients with valvar aortic stenosis with or without insufficiency. |
