case_images: Subsequent computed tomography angiography revealed a complete absence of the right coronary artery (RCA) at the level of the right coronary ostium (Figure 1).

case_images: The heart exhibits a single coronary artery (SCA) as the RCA arises from the distal left circumflex artery (LCx) (Figures 2, 3; Video 1).
case_images: Coronary computed tomography angiography-subtracted VRT reconstruction image shows origin of right coronary artery (RCA) from left circumflex artery with absence of RCA ostium. VRT: volume rendering technique; LCx: left circumflex artery; LAD: left anterior descending artery
