Abstract
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.
