Abstract

Hypertrophic cardiomyopathy has a distinct heterogeneous phenotype, which largely determines surgical tactics: extended myoectomy in the basal form of pathology, remodeling of the submitral space (transaortic or transapical), implantation of a defibrillator at high risk of sudden cardiac death. If necessary, these procedures can be supplemented with combined surgical intervention (aortic valve replacement, atrial plasty surgery and radiofrequency ablation surgery, coronary artery bypass grafting), and with an organic lesion of the mitral valve by prosthetics of the latter. In this article, we present long-term observations of patients with hypertrophic cardiomyopathy after implantation of mechanical prostheses.

Keywords: hypertrophic cardiomyopathy; combined operations; infectious endocarditis; valve replacement
