DYNAMIC CHANGES OF MITRAL APPARATUS IN ACUTE MYOCARDIAL INFARCTION WITH ISCHEMIC MITRAL REGURGITATION: PROSPECTIVE 3D QUANTITATIVE ECHOCARDIOGRAPHIC STUDY

Background: Ischemic mitral regurgitation (IMR) when chronic, involves flat and adynamic mitral annulus but IMR mechanisms in acute myocardial infarction (MI) are not known. Methods: We prospectively performed 3D echocardiography (3DE) 1.8±1.0 days after a first MI, in 2 groups of consecutive
