A straightforward tricuspid valve repair technique is illustrated here, which may be employed either for functional (normal valve with dilated annulus) or for primary or organic (Ebstein's anomaly, leaflet retraction/tethering and chordal malposition/tethering, with annular dilatation) tricuspid valve incompetence and for moderate and severe degrees of incompetence, without any residual regurgitation or reoperation. The basic principle is to reduce the distance between the coapting leaflets in a manner in which the most mobile leaflet, which is usually the anterior, could coapt to the opposite leaflet, by creating two orifices, ensuring valve competence. Additionally, it reduces annular dilatation and lessens tricuspid valve leaflet tethering, thereby stabilizing the annulus and increasing leaflet coaptation.
这里展示了一种直截了当的三尖瓣修复技术，可用于功能性（瓣叶正常但瓣环扩张）或原发性或器质性（Ebstein 畸形、瓣叶回缩/连枷、腱索异常/连枷，伴瓣环扩张）三尖瓣关闭不全，以及中重度关闭不全，且无任何残余反流或再次手术。基本原理是通过创建两个孔来缩小靠拢的瓣叶之间的距离，使最活动的瓣叶（通常是前瓣）能够与对侧瓣叶靠拢，从而确保瓣叶功能正常。此外，它还可以减小瓣环扩张程度，减轻三尖瓣瓣叶连枷样运动，从而稳定瓣环并增加瓣叶对合。
