Which coronary artery territory is associated with the wall motion abnormality demonstrated in this video?

The echocardiographic video shows hypokinesis or akinesis of the inferolateral wall of the left ventricle. This myocardial territory is predominantly supplied by the left circumflex coronary artery.

The right coronary artery primarily supplies the inferior wall and right ventricle. The left anterior descending artery supplies the anterior and septal walls. The posterior descending artery supplies the inferior wall, usually supplied by the right coronary artery or sometimes the circumflex.

These segmental coronary territories are described in ASE stress echocardiography and regional wall motion assessment guidelines【12:ASE Stress Echocardiography Guidelines†p.300-310】【16:Textbook of Clinical Echocardiography, 6e†p.380-385】.
