Ischemic Mitral regurgitation, unlike those with a primary commitment of the valves and subvalvular apparatus, has particular characteristics that need an analysis and boarding with a different and special vision by the cardiologist. Was made an overhaul of medical publication from January 1995 to February 2007 with the key words “ischemic mitral regurgitation” and were selected a total of 49 articles related to ischemic mitral regurgitation epidemiology, evaluation of its mechanisms and the corresponding therapeutic techniques. Several mechanisms have been described: displacement, elongation or rupture of papillary muscle, as well as the expansion and deformation of the mitral ring. Different techniques directed to correct each one of these mechanisms have been developed: Post myocardial infarction remodeling prevention, papillary muscle relocation or repair, mitral chordae tendineae liberation or translocation, valve repair and valve replacement, among others. The suitable evaluation and individualized identification of the pathological mechanisms involved in the genesis of ischemic mitral regurgitation by de cardiologist is determinant for to choose the best therapy. Long term following of some therapeutic techniques is necessary for to know its effectiveness.
