title: Growth of an aorta-coronary anastomosis. An experimental study in pigs.
abstract: The influence of growth of an aorta-coronary anastomosis, comparable to the coronary translocation anastomosis during the arterial switch operation, was studied in pigs. The anastomosis between the right coronary artery and the aorta did not grow, and this lack of growth may result in stenosis. With another technique, by which the coronary artery was excised with a cuff of aortic wall, the effects caused by absence of growth were circumvented and a normal-sized coronary ostium was present after growth. However, when no cuff was used, stenosis occurred at the suture line and caused growth retardation of the animal as well as histologic damage to the right ventricle.
