Case report demonstrates delayed diagnosis of tricuspid papillary muscle rupture in severe blunt chest trauma, highlighting transesophageal echocardiography for early structural heart evaluation.
We present a case of delayed diagnosis of traumatic tricuspid valve rupture in a patient who was emergently brought to the operating room for repair of lacerations to the heart and liver without intraoperative transesophageal echocardiography (TEE).Initial postoperative transthoracic echocardiography (TTE) did not show structural pathology.One week later, TTE with better image quality showed severe tricuspid regurgitation.Subsequently, TEE clearly demonstrated rupture of the anterior papillary muscle and flail anterior tricuspid leaflet.The case description is followed by a brief discussion of the utility of TEE in the setting of blunt thoracic trauma.
