Rupture of left ventricular wall (LVWR) following mitral replacement (MVR) is rare (0.5 to 7.3% of all MVR). Two "types" of LVWR have been recognized and attributed to technical errors during MVR and/or to co-existing unfavourable conditions. The two types are precisely located, and appear "early" during operation, at discontinuation of cardiopulmonary bypass (CPB). Miller et al. have described a "third type" LVWR which depends primarily on local conditions, is located between the other two and occurs "late". Successful repair is rare. The outcome is favourably influenced by intraoperative recognition. This paper reports two LVWRs "type III" which occurred among 282 MVR (0.7%) done in our Department since 1977. Both were successfully repaired respectively 12 (and again 48) and 15 hours after MVRs. To the best of our knowledge these are the only cases of successful repair of a "type III" LVWR reported in the literature. On the basis of this experience some considerations are presented.
二尖瓣置换术（MVR）后左心室壁破裂（LVWR）较为罕见（占所有MVR的0.5%至7.3%）。LVWR已被识别出两种“类型”，并归因于MVR期间的技术失误和/或并存的不利情况。这两种类型位置精确，且在手术过程中“早期”出现，即在体外循环（CPB）停止时出现。米勒等人描述了一种“第三种类型”的LVWR，其主要取决于局部情况，位于另外两种类型之间且“晚期”出现。成功修复很少见。术中识别对结果有积极影响。本文报告了自1977年以来在我们科室进行的282例MVR中发生的两例“III型”LVWR（0.7%）。两例分别在MVR术后12小时（以及再次在48小时）和15小时成功修复。据我们所知，这是文献中报道的仅有的成功修复“III型”LVWR的病例。基于这一经验，我们提出了一些思考。
