Left ventricular noncompaction


Tell me about left ventricular noncompaction.

Left ventricular noncompaction is a heart muscle disorder in which the lower left chamber of the heart, which is known as the left ventricle, is not correctly developed. The left ventricle is responsible for helping the heart pump blood. Normally, the left ventricle should be smooth and firm. In the case of left ventricular noncompaction, the left ventricle is thickened and appears spongy. This thickened, spongy texture causes an impairment where the heart is unable to pump blood properly because it cannot completely contract or relax as a normal heart would.

Symptoms of left ventricular noncompaction vary. Some people may have no symptoms at all, and others could have symptoms as severe as sudden cardiac death.
