We report the case of an 8-year-old patient with severe acute mitral regurgitation and tricuspid regurgitation after a motor vehicle collision caused by traumatic injuries of the supporting structures of both valves. An echocardiogram showed avulsion of the posteromedial papillary muscle of the mitral valve and a severely prolapsed anterior tricuspid valve leaflet. In addition, there was a near-complete defect in the left ventricular side of the interventricular septum, with diffuse hematoma of the akinetic septal muscle. After emergency mitral and tricuspid valve repairs, consisting of re-implantation of the posteromedial papillary muscle and anterior tricuspid leaflet chordal support, the patient completely recovered with no residual valvular pathology.
我们报告了一例8岁患者，在机动车碰撞后因两个瓣膜的支持结构受到创伤而出现严重急性二尖瓣反流和三尖瓣反流。超声心动图显示二尖瓣后内侧乳头肌撕脱，三尖瓣前叶严重脱垂。此外，室间隔左心室侧存在近乎完全的缺损，运动减弱的间隔肌有弥漫性血肿。在紧急进行二尖瓣和三尖瓣修复后，包括重新植入二尖瓣后内侧乳头肌和三尖瓣前叶腱索支持，患者完全康复，没有残留瓣膜病变。
