Experimental study of sutureless vascular prosthesis for total artificial heart replacement

Abstract

Sutureless vascular prosthesis with quick connector was utilized for outflow side of total artificial heart surgery in order to saving time and decrease surgical bleeding. Four calves were operated with this method. Cardiopulmonary bypass time was shortened significantly and there was less postoperative bleeding compared with suture method. Immediate postoperative course was satisfactory in all calves and one survived 34 days which was the longest in our laboratory. There was no discouraging findings macroscopically and histopathologically in aorta and Pulmonary artery.
