A 70-year-old man was referred for recent-onset angina. The ECG showed a right-axis deviation and signs of an old anterior infarction with loss of R waves in leads V1 through V5. Chest radiograph demonstrated a markedly enlarged heart, which was shifted to the left side with discrete signs of pulmonary congestion. Transthoracic echocardiography, which was limited by poor imaging quality, revealed a normal left ventricular cavity with reduced ejection fraction (40%) due to hypokinesia of the anterior wall. Coronary angiography showed the dominant RCA to originate from the left sinus of Valsalva. It coursed between the aorta and the pulmonary artery to the right (Figs …
