Figures

• 

  Fig. 1. A. The electrocardiogram showed ST-segment depression in leads V3-V6 and D1-aVL. B. Coronary angiogram in the right caudal view shows the left coronary artery, circumflex artery and intermediate artery. C. Coronary angiogram in the left anterior oblique cranial view shows the circumflex artery and right coronary artery originating from right sinus of Valsalva. (CX: circumflex artery, IM: Intermediate artery, LAD: left anterior descending artery, LSV: Left sinus of Valsalva, RCA: Right coronary artery, RSV: Right sinus of Valsalva)

  Fig. 2. The electrocardiogram showed no ST-segment depression or elevation

  Fig. 3. A. Coronary angiogram in the left caudal view shows the left coronary artery tree with a circumflex artery. B. Coronary angiogram in the left anterior oblique cranial view shows the circumflex artery and right coronary artery originating from right sinus of Valsalva. C. The significant lesion, in the left anterior oblique cranial view, shows the circumflex originating from right sinus of Valsalva. D. After stenting the significant lesion, in left anterior oblique view shows the circumflex artery originating from right sinus of Valsalva (CX: circumflex artery, LAD: left anterior descending artery, LSV: Left sinus of Valsalva, RCA: Right coronary artery, RSV: Right sinus of Valsalva)
