Which is most likely the culprit coronary artery in a patient who presents with anteroseptal...

Comprehensive and Detailed Explanation From Exact Extract:

Anteroseptal hypokinesis is most often due to ischemia or infarction in the left anterior descending (LAD) artery territory, a major branch of the left coronary artery. The LAD supplies the anterior wall and the interventricular septum.

The right coronary artery generally supplies the inferior wall and right ventricle. The circumflex artery supplies the lateral wall. The posterior descending artery supplies the inferior wall.

This coronary artery distribution and wall motion correlation is fundamental in stress echocardiography and ischemic heart disease assessment as detailed in ASE guidelines and clinical echocardiography references【12:ASE Stress Echocardiography Guidelines†p.300-310】【16:Textbook of Clinical Echocardiography, 6e†p.380-385】.
