Twenty-seven cases of ruptured chordae tendineae have been discovered during surgery for mitral regurgitation (9,3 %) : the highest incidence of ruptured chordae tendineae has been found among pure mitral insufficiency (36 %). In thirteen cases, the rupture was isolated, without any other valvular lesion. The syndrome described as characteristic of rupture was present in one third of our patients : isolated cases do not differ clinically from the others but for a more frequent acute evolution. In pure or predominant mitral regurgitation, surgery seems needed when clinical aggravation, acute or progressive, cannot be explained by arrhythmia, anaemia, pulmonary embolism, hyperthyroidism.
在二尖瓣反流手术中发现了27例腱索断裂病例（9.3%）：在单纯二尖瓣关闭不全病例中腱索断裂的发生率最高（36%）。13例为孤立性断裂，无其他瓣膜病变。三分之一的患者出现了被描述为腱索断裂特征性的综合征：孤立性病例与其他病例在临床上并无差异，只是急性进展更为常见。在单纯或主要为二尖瓣反流的情况下，当临床症状急性或进行性加重无法用心律失常、贫血、肺栓塞、甲状腺功能亢进解释时，似乎需要进行手术。
