Normal coronary anatomy and anomalous origin of left coronary artery (LCA). A: The normal origins of the coronary arteries are shown, with the LCA arising from the left sinus of Valsalva. B: The anomalous origin of the LCA from the right sinus of Valsalva is depicted showing 2 variants. The “benign” variant (dashed lines) runs in the septum anterior to the pulmonary artery (PA), whereas the “malignant” version runs posterior to the PA and between the annuli of the aorta and PA, creating a risk for compression of the LCA and compromise of blood flow to the myocardium. RCA, right coronary artery; LAD, left anterior descending artery. Artwork provided by Steven J.

Cardiac computed tomography scan (3-dimensional reconstruction). The pulmonary artery (PA) was selectively removed from volume rendering images to demonstrate an interarterial course of the left main (LM) coming off the right coronary cusp with the right coronary artery (RCA). LAD, left anterior descending artery; LCx, left circumflex artery.

Cardiac computed tomography scan. Left main artery (LM) and right coronary artery (RCA) originated from the right coronary cusp. The course of the LM between the aorta (Ao) and the pulmonary artery (PA) is seen clearly. DscAo, descending aorta; LA, left atrium; LV, left ventricle; PV, pulmonary vein.
