The left ventricle free wall is composed of the area of the left ventricular wall not in contact with the interventricular septum and is not part of the apex. In an attitudinally correct position the free wall is lateral and posterior.

Importance in cardiovascular diseases:
There is risk of left ventricular free wall rupture associated with acute myocardial infarction. The rupture can be immediately catastrophic or can lead to slower complications, such as cardiac tamponade. Rupture of the free wall requires surgical repair. Other diseases that can occur in the free wall include the family of diseases known as cardiomyopathies; such as dilation or hypertrophy. Most cardiomyopathies are idiopathic, but are generally suggested to be inherited, due to toxins, infections, or inflammation. Dilated cardiomyopathy refers to remodeling of the tissue in an unfavorable manner. Specifically, the heart dilates, like a balloon being blown up, leading to a more rounded profile and thinner walls. In hypertrophic cardiomyopathy, the muscle becomes enlarged and can reduce stroke volume. Both reduce the efficiency of the heart and increase the risk of arrhythmia and sudden cardiac death.

Importance of device delivery:
Possible damage during transapical procedures and left ventricular lead placement may occur in the free wall.
