A pulse duplicator replicates parts of the circulatory system. Many pulse duplicators model only half the heart, commonly the left atrium and ventricle, in order to test the mitral and aortic valves. A common design to model the heart uses a piston to simulate the contraction and expansion of the heart.
Mitral valve repair is mainly used to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. [citation needed] A mitral balloon valvuloplasty enlarges the valve opening to allow greater oxygenated blood flow into the left ventricle, and since severe mitral regurgitation can be a major complication, degrees of stenosis, regurgitation, and valve anatomical features are taken ...
