Side of the heart that end up straining the entire system.īased on the severity of the problem, leaking valves may require surgical repair or replacement. Tricuspid regurgitation is more commonly caused by an enlarged lower chamber on the right side of the heart, but it may also develop in response to other valve problems on the left.Pulmonary or pulmonic regurgitation is more rare and is usually a result of other problems like pulmonary hypertension.Aortic valve regurgitation may stem from a congenital heart defect, complications of an infection or other more rare causes.Stresses the basic issues and problems facing journalists and the mass media. Mitral regurgitation is leakage of blood backward through the mitral valve each time the left ventricle contracts. A good journalist will collect facts, research and investigate the subject.
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.
