Isolated right ventricular infarction complicated by ventricular septal defect

Right ventricular infarction is frequently seen with inferior myocardial infarction, but it rarely presents in isolation. We describe a case of isolated right ventricular infarction complicated with ventricular septal defect. Clinical, hemodynamic, echocardiographic, and surgical features are discussed. Twenty months following surgical repair of the ventricular septal defect and two vessel coronary artery bypass surgery, the patient continues to do well and is free from angina and exertional dyspnea.
