Overview
If an artery arises from the left main coronary artery between the left anterior descending artery (LAD) and the left circumflex artery (LCX), it is known as the ramus intermedius.
Epidemiology and Demographics
The ramus intermedius occurs in 37% of the general population, and is considered a normal variant.
Additional Images
Shown below are an animated image and a static image depicting the median ramus (MR).
