Blood flows from the right and left atria through the tricuspid and mitral valves, which open to allow blood to flow into the right and left ventricles. These valves then close to prevent blood from flowing back into the atria. Once the ventricles have filled with blood, they begin to contract, forcing the pulmonary and aortic valves to open. Blood then flows to the pulmonary artery and aorta. The pulmonary artery carries deoxygenated blood from the heart to the lungs. This can be caused by a leakage of blood, which is called regurgitation, a narrowing of the valve opening, which is called stenosis, or a combination of regurgitation and stenosis.
