In general the anterolateral wall is the anterior and lateral walls of the myocardial tissue of the heart. The heart is divided into anterior, anterior interventricular, lateral, posterior, and inferior walls depending on the part of the ventricle. Both the anterior and anterior interventricular walls refer to the myocardial tissue anterior to the left ventricle, the anterior wall is the relatively free portion of the myocardial tissue, the lateral wall is the myocardial tissue on the side, the posterior wall is the myocardial tissue at the back, and the inferior wall refers to the myocardial tissue on the offside. The anterolateral wall can be understood as the anterior wall of the left ventricle, which receives blood supply from the anterior descending branch, and partially from the echogenic branch, which is derived from the left main stem. When there is a stenosis of the left main stem or anterior descending branch, it will lead to myocardial ischemia of the anterior wall, and in severe cases, it will lead to infarction of the anterior wall, affecting the ejection function of the left ventricle, which will easily lead to acute left heart failure. When the above situation occurs, it is recommended to consult a doctor in time for treatment under the doctor’s guidance.
