[Mitral valve remodeling in patients with acute myocardial infarction and ischemic mitral regurgitation].

We have studied alterations of mitral valve geometry and quantitative parameters of mitral regurgitation in 130 patients with acute myocardial infarction in acute and subacute stages of the disease. Quantitative data of mitral regurgitation have been assessed using two quantitative Doppler techniques--proximal isovelocity surface area method (PISA-method) and quantitative Doppler technique (Q-DE-method). As a result of the research we have received data showing that in patients with acute myocardial infarction and ischemic mitral regurgitation mitral valve remodeling occurs with deformation of mitral structures inducing mitral regurgitation. We have observed correlation between degree of ischemic mitral regurgitation and structural valve alteration in patients with acute myocardial infarction.
