Figure 2.

Anomaly of the origin of the right coronary from the left anterior coronary sinus, with a course between the pulmonary artery and the aorta. (a) CCTA volume rendered cardiac transparency images showing anomaly of origin and course; the right coronary anomaly originates from the left coronary sinus with an anomalous course between the left pulmonary artery and the aorta. Normal origin of the left main coronary artery from the posterior portion of the left coronary sinus with a normal trajectory. Intermediate filiform branch is present; (b) CCTA axial contrast-enhanced image at the aortic root showing anomaly of the origin and course; the right coronary abnormally originates from the left coronary sinus; (c) CCTA axial contrast-enhanced image at the aortic root showing RCA with an anomalous course between the pulmonary artery and the aorta; (d) CCTA curved planar reformatted image of the RCA; (e) CCTA curved planar reformatted image of the RCA origin; (f) CCTA vessel cross-section image of the RCA with an anomalous course between the pulmonary artery and the aorta.
