Reoperations for a dysfunctional mechanical aortic valve prosthesis are usually performed with a repeat sternotomy. Reopening the chest may be associated with a heart structure tear, bleeding, excessive transfusion, and a possible unfavorable outcome. Experience performing a redo aortic valve replacement with a minimally invasive approach and avoiding lysis of the pericardial adhesions is growing. We describe a redo aortic valve replacement procedure performed because of subvalvular pannus formation in a patient with a mechanical prosthesis. A partial J-shaped hemisternotomy at the 3rd intercostal space was performed; the ascending aorta was exposed and the valve was replaced with a sutureless bioprosthesis. The video tutorial shows the surgical approach, cardiopulmonary bypass solutions, and sutureless valve deployment.
因机械主动脉瓣假体功能障碍而进行的再次手术通常需要进行重复的胸骨切开术。再次打开胸腔可能会导致心脏结构撕裂、出血、过度输血以及可能出现不良后果。目前,采用微创方法进行再次主动脉瓣置换术并避免松解心包粘连的经验正在不断积累。我们描述了一位机械假体患者因瓣下假性瘤形成而进行的再次主动脉瓣置换术。在第 3 肋间隙进行部分 J 形半胸骨切开术;显露升主动脉,并使用无缝线生物假体置换瓣膜。该视频教程展示了手术入路、体外循环解决方案和无缝线瓣膜展开。
