MID-TERM AND LONG-TERM OUTCOMES OF FUNCTIONAL MITRAL INSUFFICIENCY INTERVENTIONAL TREATMENT IN PATIENTS WITH CARDIOMYOPATHY

The article presents the outcomes of treatment of patients with cardiomyopathy and pronounced functional mitral insufficiency 6, 12 and 24 months after MitraClip device implantation. We observed that 6 months after the intervention, there was regression of left heart chamber remodeling, as well as positive dynamics of right ventricular ejection fraction and pulmonary artery pressure against the background of mitral valve improvement. The achieved effect of improved intracardiac hemodynamics persisted in 12 months after mitral valve clipping. After 12 months, there were signs of left ventricular remodeling without significant changes in valve characteristics and left atrial parameters. During the first 6 to 12 months after MitraClip implantation, the distance walked in the 6-minute walk test and peak oxygen consumption increased, with retention of high values of these indicators in 24 months of follow-up.
