  Fig. 1 Coronary angiography showed there were no significant lesions at LAD and LCX (A). However, RCA could not be found at its usual location. It originated from left sinus of Valsarva (white arrow) close to the left main coronary artery with diffuse minimal stenosis at its proximal segment (B). But there was no significant stenosis at ostium of RCA. LAD: left anterior descending coronary artery, LCX: left circumflex artery, RCA: right coronary artery.

• 

  Fig. 2 MDCT showed RCA originated from left sinus of Valsalva (white arrow), separate from the left main coronary artery, and courses anteriorly between aortic root and main pulmonary trunk (A). The maximum intensity projection image showed an acute-angled takeoff of the RCA (white arrow) from the ascending aorta and small orifice of RCA (B). Operative findings showed RCA ostium with small slit-like orifice was originated left sinus of Valsalva with acute angle and proximal portion of RCA (white arrows) was located beside the commissure between the right and left cusps which is embedded in aortic wall (C). After operation (unroofing procedure), follow-up MDCT and coronary angiography showed good patency of RCA (D and E).
