Research of last three-decades has shown that the mitral annulus starts contracting during atrial systole which significantly prevent early mitral regurgitation (MR). MR can be acute or chronic, and primary, or secondary or mixed; their etiologies, mechanisms and natural progression are very different and have clinical implications. A leaflet perforation, a rupture of chorda tendinea or papillary muscle and a torn leaflet after balloon mitral valvotomy can result in acute severe MR. The patients of acute severe MR present in pulmonary edema and cardiogenic shock and often need urgent surgical intervention. Primary MR is a disease of the mitral valve apparatus and secondary to valve degeneration, whereas secondary MR is a disease of the left ventricle secondary to coronary artery disease and dilated cardiomyopathy. The other causes of secondary MR include mitral annular dilation secondary to atrial fibrillation and restrictive cardiomyopathy, dys-synchrony due to bundle branch block, right ventricular pacing and hypertrophic cardiomyopathy. The treatment strategy differs for primary and various subsets of secondary MR; hence, a thorough knowledge of the etiology, mechanisms and pathogenesis of MR is necessary to select appropriate management strategy and to decide when to intervene.
