How does Lipton et al. divide the two main types of single coronary arteries?
Single coronary arteries are typed as right or left depending on whether it originates from the right or left coronary sinus, respectively.
The left main coronary artery (LMA) takes off from the left aortic sinus and bifurcates into a left anterior descending artery (LAD) and left circumflex artery (LCx).
The LMA is large and patent.
The LAD wraps around the cardiac apex (type III vessel).
The LCx extends to and traverses the base of the heart, then terminates at the right atrioventricular groove. A prominent marginal artery is seen.
The right coronary artery (RCA) is absent.
Mild coronary atherosclerosis with no significant stenoses.
