title: Gunshot wounds: causing myocardial infarction, delayed ventricular septal defect, and congestive heart failure.
abstract: Penetrating chest trauma can cause a wide variety of cardiac injuries, including myocardial contusion, damage to the interventricular septum, laceration of the coronary arteries, and free-wall rupture. Herein, we describe the case of a 21-year-old man who presented with congestive heart failure, which was secondary to an old myocardial infarction and complicated by the delayed formation of a ventricular septal defect. All of these conditions were attributable to multiple gunshot wounds that the patient had sustained 6 months earlier. Left ventricular angiography showed an apical aneurysm; a large, muscular, ventricular septal defect; and 19 gunshot pellets in the chest wall. Three months after aneurysmectomy and surgical closure of the septal defect, the patient had recovered fully and was asymptomatic.This case reaffirms the fact that substantial cardiac injuries can appear months after chest trauma. The possibility of traumatic ventricular septal defect should be considered in all multiple-trauma patients who develop a new heart murmur, even when overt chest-wall injury is absent.
