Aortic valve regurgitation may stem from a congenital heart defect, complications of an infection or other more rare causes.Mitral regurgitation is leakage of blood backward through the mitral valve each time the left ventricle contracts.Read more about regurgitation and specific valves: Valve regurgitation can come on suddenly or it may develop gradually over decades. Watch a mitral valve regurgitation animation. Leaking valves can cause the heart to work harder to pump the same amount of blood. Oxygen-rich blood either flows out through the aorta to the body – as it should – or it flows backward from the aorta through the defective valve into the left ventricle when the ventricle relaxes. Some blood flows from the ventricle through the aortic valve – as it should – and some blood flows back into the atrium through the defective valve.Ī leaking aortic valve allows blood to flow in two directions. Blood leaks through the leaflets that don't close correctly.Ī leaking (regurgitant) mitral valve allows blood to flow in two directions during the contraction.Blood flows back through the valve as the leaflets are closing, or.
It can cause the heart to work harder and it may not pump the same
At other times valve regurgitation places a strain on the heart. Sometimes the condition is minor and may not require treatment. Regurgitation is the name for leaking heart valves. National Hypertension Control Initiative.Pets and Your Health / Healthy Bond for Life.
