BACKGROUND: Intracardiac shunts are rare but very serious lesions after non-penetrating chest trauma. Their diagnosis is difficult. This pathology often goes unrecognized in the context of multiple trauma. CASE REPORT: We report the case of a 21-year-old man involved in a motor vehicle crash who presented with multiple injuries including myocardial contusion, severe brain injury, multiple pelvic fractures, closed femur fracture, bilateral lung contusion with a right pneumothorax, and intra-abdominal injuries. Three days after the initial event, a new cardiac murmur and complete heart block appeared. Transthoracic echocardiography (echo) followed by transesophageal echo revealed a high-velocity flow communication between the left ventricle and the right atrium. The patient underwent delayed cardiac surgery due to other unstable injuries. The hospital course was prolonged but favorable, and the patient left the hospital 1 month later without any neurologic or cardiologic after-effect. CONCLUSION: This case highlights the potential for cardiac complications to occur in any patient with serious thoracic trauma. Transesophageal echo should be performed on any trauma patient with electrocardiographic abnormalities.
