Isolated mitral valve injury from non-penetrating cardiac trauma was low in incidence. A successfully operated case of a patient with acute mitral insufficiency from non-penetrating cardiac injury due to a traffic accident was reported and discussed. This isolated mitral valve lesion, of which the posterior leaflet was torn away from the annulus with intact chordae tendineae and papillary muscle, was very rare in the literature. And, particularly, the preoperative non-invasive findings such as echocardiogram and ACG were mostly useful and important in our case. This case was the fourth successful repaired case on blunt isolated mitral valve injury in the literature.
非穿透性心脏创伤导致的孤立性二尖瓣损伤发病率较低。本文报告并讨论了一例因交通事故导致非穿透性心脏损伤引起急性二尖瓣关闭不全且手术成功的病例。这种孤立性二尖瓣病变，即后叶从瓣环撕脱而腱索和乳头肌完整，在文献中非常罕见。而且，特别是在我们这个病例中，术前的非侵入性检查结果如超声心动图和心电图大多非常有用且重要。该病例是文献中第四例钝性孤立性二尖瓣损伤修复成功的病例。
