Right ventricle

The right ventricle is the chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs. 

The right ventricle is one of the heart’s four chambers. It is located in the lower right portion of the heart below the right atrium and opposite the left ventricle.

As deoxygenated blood flows into the right atrium, it passes through the tricuspid valve and into the right ventricle, which pumps the blood up through the pulmonary valve and through the pulmonary artery to the lungs.

Right side heart failure is a condition when the right side of the heart can no longer pump blood efficiently. It’s also known as congestive heart failure because as the right side of the heart loses it strength, blood can back up or become congested.

Arrhythmogenic right ventricular dysplasia is a rare genetic defect where the right ventricle’s muscle is replaced with fat and scar tissue. This can lead to a rapid heartbeat and other serious problems.

Another congenital heart defect, double outlet right ventricle, occurs when the aorta rises from the right ventricle instead of the left ventricle. This condition is usually treated with surgery.
