Magnetic Resonance Imaging of a Posttraumatic Myocardial Infarction and Ventricular Septal Defect With a Closure Device in Place

Abstract

A 16-year-old boy sustained blunt trauma as a passenger in a high-speed motor vehicle accident 2 years earlier. Before the accident, he was healthy with no known cardiac disease or murmur. On admission after the accident, he was noted to have a loud IV/VI holosystolic murmur along the left sternal border. One month after admission, an echocardiogram revealed a 1.5-cm muscular ventricular septal defect with a left-to-right shunt, enlargement of the right atrium and ventricle, elevated pulmonary arterial pressure, and moderate tricuspid regurgitation (Figure 1 and Movie I). Figure 1. Delayed contrast enhancement in the short-axis plane demonstrates both sides of the …
