Mitral valve annuloplasty has been the gold standard for treatment of functional mitral valve regurgitation. However, annuloplasty for functional mitral regurgitation may cause augmented posterior leaflet tethering, which results in functional anterior prolapse. Herein we added papillary muscle heads focalization for such patients. All separated papillary muscle heads are sutured together, and the roots of chordae at each papillary muscle are unifocalized on both sides. Stitches are positioned at the same distances from corresponding leaflet edges to adjust the height of leaflet edges in each segment. This is a simple and effective technique to correct for functional anterior prolapse after annuloplasty.
二尖瓣环成形术一直是治疗功能性二尖瓣反流的金标准。然而，功能性二尖瓣反流的瓣环成形术可能导致后瓣叶的牵拉力增加，从而导致功能性前瓣脱垂。在此，我们为这类患者增加了乳头肌头部固定术。将所有分离的乳头肌头部缝合在一起，将每个乳头肌的腱索根部在两侧进行单一化处理。缝线的位置与相应瓣叶边缘的距离相同，以调整每个瓣叶节段的瓣叶边缘高度。这是一种简单有效的技术，可以纠正瓣环成形术后的功能性前瓣脱垂。
