A 39-year-old male was transferred to the hospital after having had an accident in a collision with another motorcycle. On arrival, the patient was found tachypneic, tachycardic, hypotensive, and stuporous. There were signs of head trauma, thoracic contusion, and long bone and pelvic fractures. No serious injuries were seen on a computed tomography (CT) scan of the head but a chest CT scan revealed a bilateral pneumothorax and mediastinal hematoma. Therefore, he underwent further workup to rule-out blunt cardiac injury (BCI). An ECG showed a complete right bundle branch block (Fig. 1A) and troponin I levels were found raised up to 24 ng/mL, which prompted to perform an echocardiogram that disclosed a partial rupture of the interventricular septum (PRVS) (Fig. 1B) without evidence of septal defect (VSD) on color Doppler (Fig. 1C). A second review of the chest CT scan also revealed such rupture (Fig. 1D). The patient became stable after tube thoracostomy, surgical fixation of bone fractures, and admission to the intensive care unit for mechanical ventilation. The cardiac surgeon declined any surgical intervention since there was no VSD. At 3-year follow-up, he remains free of symptoms of right ventricular failure. BCI is the cardiac damage resulting from thoracic trauma and should always be entertained as an impending condition in patients with blunt chest trauma. When both ECG and cardiac troponin I are normal at 8 h after admission, BCI is certainly excluded. 1 However, those patients with persistent hypotension, hypoxemia, heart block or arrythmias warrant an echocardiogram2 in order to rule out pericardial tamponade and valvular or myocardial injury. Although conservative management of PRVS has been previously reported,3 late rupture remains a concern.
