Abstract
The classical technique involved in performing an aortopexy consists of placing the sutures for traction to the posterior surface of the sternum through the wall of the aorta. These sutures are deliberately passed through the adventitial and medial layers of the aortic wall in an attempt to avoid entering the intimal layer. The traction forces exerted on the aorta in anchoring it to the back of the sternum are therefore distributed over a relatively small surface area. The sutures may cut out and the likelihood of long-term permanent damage to the wall of the aorta owing to aneurysmal degeneration cannot be completely dismissed. The dacron-patch aortopexy was devised to minimize trauma to the wall of the aorta by: 1. Attaching the patch to the aortic wall by means of a number of fine sutures 2. Passing the heavy sutures for the aortopexy through the dacron patch Traction on the aorta is evenly distributed over a large area rather than concentrated on three or four specific points.
