A 70-year-old man was referred to our hospital because of symptoms of congestive heart failure. The initial echocardiographic study revealed a dilated and poorly contractile left ventricle, a markedly dilated left circumflex coronary artery (LCx), and an enormously dilated anomalous vessel inferior to the right atrium (RA). Color Doppler flow mapping documented a turbulent flow in the LCx, draining into the RA through the anomalous vessel. An LCx-RA arteriovenous fistula was suspected. Multislice spiral computed tomography (MSCT) imaging was performed using a Somatom Volume Zoom (4-detector-row, Siemens, Stuttgart, Germany) with collimation 1.0 mm, table feed 1.5 mm/rotation, 140 kV, 320 mA, and gantry rotation time 500 ms. Our scan protocol and image reconstruction method have been reported previously. 1 Metoprolol (40 mg) was
