This report describes the ability of cardiac magnetic resonance (MR) imaging to depict an unusual cardiac defect. A type of ventricular septal defect called the Gerbode defect, which results in a communication between the left ventricle and the right atrium, is presented. To the authors' knowledge, this is the first time cardiac MR imaging has been utilized to characterize this defect.
