This is an angiogram of a non-dominant right coronary artery in a patient with a dominant left circumflex artery. The RCA is very small, compared to the usual. This patient is one of about 15 - 18% of the population whose circumflex artery perfuses the posterior/nferior wall of the left ventricle.

This is an angiogram of a left coronary artery (LCA). The circumflex artery, labelled CX, is dominant, meaning that it connects to the posterior descending artery and perfuses the posterior and inferior walls of the left ventricle. Approximately 15-18% of the population has a dominant circumflex artery. In about 80-85% of people, the right coronary artery (RCA), perfuses the inferior wall.
