case_images: (A) and (B) Sagittal and axial oblique maximum intensity projection (MIP) CTCA images revealing a single ostium in the right sinus of Valsalva giving rise to the left main coronary artery (LMCA - red arrow) and the right coronary artery (RCA -green arrow) (C) 3D volume rendered image visualizing the anomalous common origin of the LMCA (red arrow) and RCA (green arrow). The profoundly long LMCA follows a course anterior to the RVOT and then splits to the left anterior descending artery and the circumflex artery.

case_images: However, an unexpected finding was the presence of a coronary artery anomaly: both the LMCA and right coronary artery (RCA) originated from a single ostium in the right sinus of Valsalva (Figs. 1A and B). The LMCA followed a long course anterior to the right ventricular outflow tract (RVOT) before bifurcating into the left anterior descending (LAD) and left circumflex (LCx) arteries (Fig. 1C).
