Abstract

The article provides an overview of the published data on the possibilities and prospects for using the method of Doppler Tissue Imaging (DTI) in patients with coronary heart disease with ischemic mitral regurgitation (MR). The main concepts of the pathophysiology of ischemic MR, mechanisms of development of asymmetric and symmetric types of ischemic MR are considered in the article. The principles and possibilities of quantitative methods for the study of myocardial function based on the pulse-wave mode of DTI are briefly presented, as well as estimates of Strain and Strain Rate of the myocardium. The possibilities of DTI in the study of myocardial function for various types of ischemic MP, in the evaluation of the function of the papillary muscles, in the evaluation of mechanics and functions of the left atrium, and in the prediction of the development of cardiac failure in the postoperative period in patients with MP are considered. Potentially, the study of LV myocardial deformation parameters and mitral valve structures (papillary muscles, left atrium myocardium), in addition to existing methods, can be used to predict the dynamics of ischemic mitral regurgitation after myocardial revascularization, and also help in predicting the outcome of reconstructive intervention on the mitral valve.
