摘要

Prolongation of the ischemic time in heart transplantation adversely affects the performance of the donor heart. We compared the impact of ischemic time in 30 patients who had the conventional bicaval method with declamping just after the last anastomosis (group A) and 28 who had a modified short crossclamp technique with declamping after left atrial stump, aorta, and inferior vena caval anastomosis (group B). In the operating room, 4 (13.3%) group A patients need one inotropic and 26 (86.6%) need 2 or more; one (3.3%) needed intraaortic balloon pumping. In group B, one inotropic was used in 7 (25%) patients, 4 (14.2%) need 2 or more, and 17 (60.7%) needed no inotropic. Mean crossclamp time was 80.5 ± 4.7 min in group A and 62.4 ± 5.8 min in group B. Weaning from bypass was faster in group B. Transesophageal echocardiography at the end of the operation showed more complete de-airing in group B. There were no significant differences in intensive care unit stay or the incidence of postoperative neurologic complications between the 2 groups. Easier separation from bypass, even without a hot shot, and better echocardiographic systolic parameters postoperatively are the advantages of this modified technique.
