目的描述一种新型心房牵开器，并比较微创二尖瓣修复术中左心房牵开的两种方法。方法对 5 具猪尸体进行左心房牵开，以评估微创心房牵开器和 HeartPort 心房牵开器的性能（二尖瓣环可触及的百分比）、遇到的并发症、易用性和手术时间。 HeartPort 和微创心房牵开器分别为 93.0%（标准误差 = 3.2）和 92.7%（标准误差 = 3.3），差异为 0.3%（标准误差 = 2.2%，P = .8832，df = 34）。微创心房牵开器出现组织损伤1例，HeartPort牵开器出现组织损伤2例。 HeartPort 和微创心房牵开器的牵开器放置和二尖瓣环暴露的平均手术时间分别为 107.4 秒和 39.2 秒，差异为 68.2 秒 (P = .0092，df = 4)。 结论 与标准牵开技术相比，微创心房牵开器是心房牵开的合适替代方案。它提供了二尖瓣环的可比暴露，放置耗时更少，在左心房回缩内提供了主观上更多的工作容积，并且具有最小心房切开切口长度和可定制回缩的优点。
OBJECTIVESTo describe a novel atrial retractor and compare 2 methods of intraoperative left atrial retraction for minimally invasive mitral valve repair.METHODSLeft atrial retraction was performed on 5 swine cadavers to evaluate performance (percent of mitral valve annulus accessible), complications encountered, ease of use, and surgical time for the minimally invasive atrial retractor and a HeartPort atrial retractor.RESULTSEstimated accessibilities were 93.0% (standard error = 3.2) and 92.7% (standard error = 3.3) for the HeartPort and minimally invasive atrial retractor retractors, respectively, with a difference of 0.3% (standard error = 2.2%, P = .8832, df = 34). Tissue damage occurred in 1 case for the minimally invasive atrial retractor and 2 cases for the HeartPort retractor. The mean surgical times for retractor placement and mitral valve annulus exposure were 107.4 and 39.2 seconds for the HeartPort and minimally invasive atrial retractor retractors, respectively, with a difference of 68.2 seconds (P = .0092, df = 4).CONCLUSIONSThe minimally invasive atrial retractor is a suitable alternative for atrial retraction compared with standard techniques of retraction. It provides comparable exposure of the mitral valve annulus, is less time consuming to place, provides subjectively more working volume within the left atrial retraction, and has the advantage of minimal atriotomy incision length and customizable retraction.
