The preservation of the subvalvular apparatus during mitral valve replacement is necessary to maintain the geometry and function of the left ventricle. Although several complete or partial chordal preservation methods have been described, some continue to preserve only the posterior chordal attachments. This is due to a fear of possible patient prosthetic valve mismatch with many well-known chordal preservation techniques. We describe a simple method of preservation of both the leaflets and chordal attachments using a simple eversion technique. In our technique, we retain all the mitral valvular and subvalvular tissue. The excised leaflet ends are everted by the valve sutures to avoid interference with the prosthetic valve leaflets.
二尖瓣置换术中保留瓣下结构对于维持左心室的几何形态和功能至关重要。尽管已经描述了几种完全或部分保留腱索的方法，但仍有一些方法仅保留后叶腱索附着。这是因为担心许多著名的腱索保留技术可能导致患者人工瓣膜不匹配。我们描述了一种使用简单外翻技术保留瓣叶和腱索附着的简单方法。在我们的技术中，我们保留所有二尖瓣和瓣下组织。切除的瓣叶末端通过瓣膜缝线外翻，以避免干扰人工瓣膜瓣叶。
