The introduction of the first surgical prosthetic heart valves in the early 1960s made effective treatment of aortic valve disease possible. The goal of surgical aortic valve replacement is to replace the diseased aortic valve with a properly functioning, sufficiently large prosthesis while avoiding intraoperative complications such as conduction disturbances, coronary artery occlusion, or paravalvular leaks. Although most commonly, non-everting pledgeted mattress sutures are used to implant the prosthesis during surgical aortic valve replacement , interrupted single sutures without pledgets can be a useful alternative, especially in patients with a small tissue annulus, because they theoretically maximize the orifice available for flow. This tutorial discusses the surgical technique of surgical aortic valve replacement using interrupted single annular sutures.
20 世纪 60 年代初，首例外科人工心脏瓣膜的问世使得主动脉瓣疾病的有效治疗成为可能。外科主动脉瓣置换术的目的是用功能正常、足够大的假体置换病变的主动脉瓣，同时避免术中并发症，如传导障碍、冠状动脉阻塞或瓣周漏。虽然最常用的方法是在外科主动脉瓣置换术中使用非外翻褥式缝合线植入假体，但间断单缝线而不使用褥式缝线也可以是一种有用的替代方法，特别是对于组织瓣环较小的患者，因为从理论上讲，这种方法最大限度地增加了血流的有效瓣口。本教程讨论了使用间断单环形缝线进行外科主动脉瓣置换术的手术技术。
