Which territories are supplied by which coronary arteries?
The three main branches of the coronary arteries are the left anterior descending artery (LAD), the left circumflex artery (LCx), and the right coronary artery (RCA). The LAD supplies the anterior wall, including the anterolateral region; the interventricular septum; and, in most cases, the apex. The RCA supplies the inferior wall and, in a “right dominant” system, can wrap around the apex to include part of the inferoapical wall. The LCx supplies the lateral wall. Smaller branches of these major arteries can supply smaller segments of individual walls
