They are often asymptomatic, and they may be incidentally discovered on chest radiography. We present an unusual case of a patient who developed acute dyspnea and right ventricular dysfunction 30 years after coronary artery bypass graft surgery. Echocardiography showed a massive aneurysm of the SVG to the first obtuse marginal artery causing mechanical compression of the pulmonary trunk and a rapid rise in the pulmonary arterial pressure. The diagnosis was then confirmed on contrast computed tomography.
