Although sizing for mitral annuloplasty (MAP) is a critical part of mitral valve repair, no consistent method is used, and precise size adjustment is done somewhat by intuition. We developed a new original ring size tester and have been applying it to our mitral valve repair procedure. The concept is that the tester shapes the annulus into exactly the same size and form as the target annuloplasty while confirming a good leaflet coaptation with a saline test to simulate annuloplasty. This original tester provides the best ring size for MAP that is neither too large nor too small. In this paper, we introduce our original ring size tester and describe how it is used for MAP.
尽管二尖瓣环成形术（MAP）的尺寸测量是二尖瓣修复的关键部分，但目前尚无统一的方法，精确的尺寸调整在一定程度上依靠直觉。我们研发了一种新型的原创环尺寸测试仪，并已将其应用于我们的二尖瓣修复手术中。其理念是，该测试仪能将瓣环塑形为与目标环成形术完全相同的尺寸和形状，同时通过盐水测试确认瓣叶良好对合，以模拟环成形术。这种原创测试仪可为MAP提供最佳的环尺寸，既不过大也不过小。在本文中，我们介绍我们的原创环尺寸测试仪，并描述其在MAP中的使用方法。
