Inferior wall of left ventricle

The inferior wall of the left ventricle refers to the myocardial region forming the diaphragmatic surface of the left ventricle. Anatomically, it is situated adjacent to the diaphragm and lies posterior-inferior in attitudinally correct orientation, extending from the base toward the apex. This wall is typically visualized in imaging modalities such as echocardiography, especially in the parasternal short-axis and apical views, and corresponds to the segments supplied predominantly by the right coronary artery in most individuals.

The walls of the left ventricle are classically described as the anterior (or superior), posterior (or inferior), lateral, and septal (interventricular septum) walls. This nomenclature is widely used in cardiac imaging, including echocardiography, cardiac MRI, and nuclear medicine, and is reflected in the American Heart Association's 17-segment model for left ventricular analysis. The anterior wall is sometimes referred to as the superior wall for anatomical accuracy, while the posterior wall may be called the inferior wall. The lateral wall is positioned on the left side of the ventricle, and the septal wall is adjacent to the interventricular septum.
