Transradia coronary angiography showed AAORCA (A,B). AAORCA, the anomalous aortic origin of the right coronary artery; RCA, right coronary artery; LCS, left coronary sinus; LCA, left coronary artery.

AAORCA and slight coronary stenosis (Figures 1A,B; Supplementary Video 1) after trans-radial coronary angiography and recovered after 2-week symptomatic treatment with medicine.
Transthoracic echocardiography (Short-axis view at the great artery) revealed Stanford type A aortic dissection (A), avulsion of the RCA, and the RCA originating from the left coronary sinus (B). RCA, right coronary artery; AD, aortic dissection; AO, aortic; PA, pulmonary artery.

Transthoracic echocardiography showed a Stanford type A aortic dissection (AD) with the widening from the aortic sinus to the thoracic aorta, avulsion injury at the opening of the right coronary artery (RCA), and the RCA originated from the left coronary sinus (LCS) (Figures 2A,B).
Total aorta plus coronary computed tomography angiogram showed the Stanford type A aortic dissection (A-C), the RCA originated from the LCS (C,D) and coursed between the aorta and the pulmonary artery (D). RCA, right coronary artery; LCA, left coronary artery; AD, aortic dissection; AO, aortic; PA, pulmonary artery.

Total aorta plus coronary CTA clarified the Stanford type A AD involving from the aortic root to the abdominal aorta, while left and right coronary arteries originated from the LCS (Figures 3A-C; Supplementary Video 2). The RCA was abnormally distributed and walked between the aorta-pulmonary artery (Figure 3D; Supplementary Video 3).
