Mitral Regurgitation—Chronic Versus Acute: Implications for Timing of Surgery

Part of the Contemporary Internal Medicine book series (COIM, volume 3)


Normal mitral valve closure is a complex mechanism resulting from a combination of atrial and ventricular events. Effective systolic sealing of the mitral valve depends on proper function, size, position, motion, and integrity of the mitral leaflets, chordae tendineae, papillary muscles, and mitral valve annulus in the presence of a normal left atrium (LA) and a normal left ventricle (LV). Mitral regurgitation (MR) occurs when mitral valve closure is ineffective.
