Surgical repair of ruptured or elongated chordae tendineae of the mitral valve is one of the most complex reconstructive techniques in cardiac surgery. Various surgical procedures have been described to repair chordal abnormalities of the anterior leaflet of the mitral valve. This case report describes a simple repair technique with a double-armed, pledge-supported, expanded polytetrafluorethylene (PTFE) suture. A 48 year-old-man who had mitral regurgitation due to ruptured chordae tendineae of the anterior mitral leaflet underwent successful chordal reconstruction using 3--0 PTFE suture. Mitral regurgitation was completely repaired as shown by left ventriculogram and echo cardiogram more than one year postoperatively. In this experience, this procedure could be used to treat both elongated and ruptured chordae tendineae.
二尖瓣腱索断裂或延长的外科修复是心脏手术中最复杂的重建技术之一。已经描述了各种外科手术来修复二尖瓣前叶的腱索异常。本病例报告描述了一种使用双臂、带垫片支撑的膨体聚四氟乙烯（PTFE）缝线的简单修复技术。一名48岁男性因二尖瓣前叶腱索断裂导致二尖瓣反流，使用3-0 PTFE缝线成功进行了腱索重建。术后一年多的左心室造影和超声心动图显示二尖瓣反流已完全修复。根据这一经验，该手术可用于治疗腱索延长和断裂。
