BACKGROUND: Although standard bicaval techniques has become popular in orthotopic heart transplantation, distortion, bleeding, thrombosis and arrhythmia were still causes for concern. This study was designed to compare the standard bicaval techniques and modified bicaval techniques in our institution.
MATERIALS AND METHODS: A total of 70 recipients underwent orthotopic heart transplantation at our center from June 2015 to April 2019 (standard group = 24 cases, modified group = 46 cases). The average follow-up period was 46.4 ± 17.4 months. Atrioventricular cavity diameter was measured by ultrasonography and left atrial morphology was evaluated by CT-angiography and three-dimensional reconstruction.
RESULTS: Recipients in both groups were similar with pre-operative characteristics. Total ischemic, cardiopulmonary bypass and cross-clamp times were similar. The modified bicaval techniques group has a significantly fewer blood transfusion, lower post-transplant tricuspid regurgitation grade and the incidence of post-operative atrial arrhythmia than standard bicaval techniques group. CT-angiography and three-dimensional reconstruction illustrated ideal and physiologic left atrial morphological structure. Short-term survival differed significantly and the cumulative proportion of survival was significantly higher in the modified bicaval techniques group than that in the standard bicaval techniques group.
CONCLUSIONS: This study showed that modified bicaval techniques offers a better early outcome than standard bicaval techniques. The significant reduction of intraoperative blood transfusion and post-transplant tricuspid regurgitation grade in the modified bicaval techniques group may has a major impact on the short-term survival.
