MODERN PRINCIPLES OF DIAGNOSIS AND SURGICAL TREATMENT OF ISCHEMIC MITRAL INSUFFICIENCY

Abstract

The purpose of the study is to evaluate and analyze the results of surgical treatment of patients with ischemic mitral insufficiency. Material and methods. The results of the examination and surgical treatment of 35 patients with ischemic mitral insufficiency are analyzed. In the operative period, in order to identify the degree of mitral insufficiency and the valvular apparatus, an echocardiography was performed, where the diameter of the fibrous ring, the interpapillary distance, the annulopapillary distance, the area of the cusp tension, and the depth of the coaptation of the valves were determined. Results. A preoperative examination proved the presence of mitral valve insufficiency with regurgitation of varying degrees. 15 patients underwent myocardial revascularization, 20 patients underwent myocardial revascularization + various options for correction of ischemic mitral insufficiency. After the operation, a significant improvement in the spatial-geometric correlation of the LV and mitral valve by reducing the tension forces acting on the valves and in the group of patients undergoing myocardial revascularization + various options for the correction of ischemic mitral insufficiency as the elimination of regurgitation. Conclusion. In patients with ischemic heart disease after echocardiographic studies, having determined the degree of mitral insufficiency with its moderate and severe degree, it is necessary to have a surgical correction of the mitral valve in its apparatus; the use of myocardial revascularization + various options for the correction of ischemic mitral insufficiency gives more tantalizing results than isolated myocardial revascularization.
