We report the case of a patient who presented with sequential rupture of two papillary muscle bellies after emergent mitral valve replacement with subvalvular apparatus preservation for acute severe mitral regurgitation and cardiogenic shock during acute myocardial infarction. We discuss the possibility that the remaining chordae may have meanwhile contributed to muscle avulsion by exerting traction on ischemic myocardium and prevented embolization of the secondarily detached papillary muscle heads.
我们报告了一例患者，该患者在急性心肌梗死期间因急性重度二尖瓣反流和心源性休克接受保留瓣下装置的二尖瓣紧急置换术后，先后出现两个乳头肌肌腹破裂。我们讨论了一种可能性，即剩余的腱索可能同时通过对缺血心肌施加牵引力导致肌肉撕裂，并防止了继发性脱离的乳头肌头部发生栓塞。
