Mitral regurgitation (MR) is a serious complication of coronary heart disease. The functional form is the most frequent, often presenting with a dynamic character. The presence, and in particular the severity of MR and its dynamic character have a major impact on the medium and long term prognosis. The mechanisms responsible for MR are complex and occur in a state of disequilibrium between traction forces and closing forces, for which the significance is partly affected by the presence of asynchrony in left ventricular contraction. The therapeutic management of these patients is difficult. In cases of proven asynchrony, implantation of a biventricular pacemaker is justified. A mitral surgical procedure may be envisaged in cases of severe MR where bypass surgery is planned. In cases of moderate MR at rest, an evaluation of its dynamic character on effort can assist with the decision to undertake combined surgery. Mitral regurgitation (MR) is a common and serious complication of ischemic heart disease. Three general forms are distinguished: MR related to acute rupture of the mitral pillar, ischemic MR and functional MR. [less ▲]Detailed reference viewed: 69 (7 ULg)
