Which coronary artery is responsible for feeding the inferoseptal wall?

The correct answer is the right coronary artery, as it supplies blood to the majority of the inferior heart structures, including the inferoseptal wall. In most individuals, the right coronary artery branches into arteries that supply the lower portion of the heart, which encompasses not only the inferior wall but also parts of the septal wall when it is involved in the right dominant coronary system.

Anatomically, the inferoseptal wall is located at the junction of the inferolateral and septal regions of the heart. Since the right coronary artery predominantly supplies the inferior wall and the majority of the interventricular septum, it plays a crucial role in maintaining perfusion in this area.

The left anterior descending artery is primarily responsible for supplying the anterior wall and the anterior portion of the interventricular septum. The circumflex artery supplies the lateral wall of the left ventricle and parts of the posterior wall but does not predominantly supply the inferoseptal region. The anterior interventricular artery is essentially another name for a branch of the left anterior descending artery and thus shares the same supply characteristics as the left anterior descending artery.

These anatomical blood supply variations underlie the importance of recognizing which artery is responsible for specific regions in echoc
