29 27 SUMMARY Vitali Alegavich Adzintsou Differentiated tactics in the surgical treatement of hypertrophic obstructive cardiomyopathy Key words: hypertrophic obstructive cardiomyopathy, septal myectomy, mitral valve replacement, left ventricle outflow tract, peak systolic gradient, mass of excised myocardium. Study objectives: to develop a differentiated tactics of surgical treatment of hypertrophic obstructive cardiomyopathy. Study methods: clinical, instrumental, statistical. Results: for the first time a comprehensive study of surgical treatment results in hypertrophic obstructive cardiomyopathy has been performed based on the belarusian cohort of patients 8-year prospective observation. The influence of myocardium mass, excised during septal myectomy without associated mitral valve replacement, on the effectiveness in decrease of left ventricle outflow tract peak systolic gradient was proved for the first time. The minimum threshold myocardial excision mass is required for achievement of optimal residual left ventricle outflow gradient was justified mathematically for the first time. It has been established that when the septal myectomy is combined with the mitral valve replacement, the residual left outflow tract gradient value does not depend on the mass of the excised myocardium, since reduction of the pressure gradient in these cases is achieved mainly due to mitral valve replacement. The absence of mitral valve replacement positive effect on left ventricle remodeling in postoperative follow-up has been established. It has been proven that mitral valve replacement is characterized by a significant number of postoperative complications and negatively affects the operated patients survival. During the late follow-up, the absence of negative influence on life quality and physical activity tolerance of mild-to-moderate residual mitral regurgitation, as well as implanted permanent pacemaker, was proved. Based on the comparative analysis of the treatment results, an algorithm for surgical tactics selection was developed. Areas of application: cardiac surgery.
