Preservation of anterior mitral leaflet papillary muscle attachments during mitral valve replacement was achieved in 20 patients by excising the central portion of the anterior leaflet and suturing the rim of leaflet tissue containing marginal chordae to the remaining edge of leaflet attached to the left atrium. This closure tacks the chordae to the fibrous trigones, opens the subvalvular area, and avoids a potentially thrombogenic or obstructive redundant leaflet ridge along the rim of an inserted valve. The technique is simple, safe, reproducible, and teachable.
20例患者在二尖瓣置换术中通过切除前叶中央部分，并将包含边缘腱索的瓣叶组织边缘缝合至附着于左心房的瓣叶剩余边缘，实现了二尖瓣前叶乳头肌附着的保留。这种闭合方式将腱索固定于纤维三角，开放了瓣下区域，并避免了沿植入瓣膜边缘形成潜在的血栓形成或阻塞性多余瓣叶嵴。该技术简单、安全、可重复且易于传授。
