Blunt thoracic trauma (BTT) and the resultant isolated mitral papillary muscle avulsion, pericardial rupture, and cardiac herniation injuries are each rarely diagnosed clinical entities. We describe the first case of combined pericardial tear with cardiac herniation and ruptured mitral papillary muscles following BTT. Preoperative transesophageal echocardiography (TEE) diagnosed the delayed mitral papillary muscle rupture while all previous diagnostic modalities failed to delineate the pericardial rupture and cardiac herniation. Particular emphasis is placed on the clinical and radiologic aspects of the case that would heighten clinical suspicion in the emergency setting where blunt cardiac injury sequelae are suspected and frequently missed.
钝性胸部创伤（BTT）以及由此导致的孤立性二尖瓣乳头肌撕脱、心包破裂和心脏疝形成损伤，均为临床罕见的诊断病例。我们描述了首例钝性胸部创伤后合并心包撕裂、心脏疝形成和二尖瓣乳头肌破裂的病例。术前经食管超声心动图（TEE）诊断出延迟性二尖瓣乳头肌破裂，而此前所有诊断方法均未能明确心包破裂和心脏疝形成。本文特别强调了该病例的临床和影像学特征，这些特征会增加在怀疑钝性心脏损伤后遗症且经常漏诊的急诊情况下的临床怀疑。
