The aortic valve and the mitral valve are the most commonly replaced valves. Pulmonary and tricuspid valve replacements are fairly uncommon in adults.
The most common valve surgical procedure is aortic valve replacement for aortic stenosis or narrowing of the aortic valve. Mitral stenosis is another condition that sometimes requires a valve replacement procedure.
Replacing a leaky valve: Aortic regurgitation, (sometimes referred to as aortic insufficiency) is another common valve problem that may require valve replacement. Regurgitation means that the valve allows blood to return back through the valve and into the heart instead of moving it forward and out to the body. Aortic regurgitation can eventually lead to heart failure.
Mitral regurgitation may also require a valve replacement. In this condition, the mitral valve allows oxygenated blood to flow backward into the lungs instead of continuing through the heart as it should. People with this condition may experience shortness of breath, irregular heartbeats, and chest pain.
