We report the case of a 24-year-old woman who was ejected 40 feet during a motor vehicle accident. Upon presentation, she was awake and alert, with a systolic blood pressure of 100 mmHg. Chest computed tomography disclosed a large pericardial effusion; transthoracic echocardiography confirmed this finding and also found right ventricular diastolic collapse. A diagnosis of cardiac tamponade with probable cardiac injury was made; the patient was taken to the operating room, where median sternotomy revealed a 1-cm laceration of the right atrial appendage. This lesion was directly repaired with 4-0 polypropylene suture. Her postoperative course was uneventful, and she continued to recover from injuries to the musculoskeletal system. This case highlights the need for a high degree of suspicion of cardiac injuries after blunt chest trauma. An algorithm is proposed for rapid recognition, diagnosis, and treatment of these lesions.enAccidents, trafficalgorithmsbiological markers/bloodblunt chest traumacardiac tamponade/etiologyechocardiography, transesophagealechocardiography, transthoracicheart atria/injuriesheart rupture/diagnosispericardiocentesistroponin/bloodwounds, nonpenetrating/diagnosis/surgeryResource Types::text::journal::journal article
