Surgical treatment of patients with obstructive hypertrophic cardiomyopathy

Abstract

To analyze in-hospital results of surgical treatment of patients with obstructive hypertrophic cardiomyopathy. There were 15 patients (8 women and 6 men) with obstructive hypertrophic cardiomyopathy and severe mitral insufficiency for the period from November 2017 to March 2019. Mean age of patients was 55.9±7.1 years. All patients had chronic heart failure NYHA class III and secondary coronary insufficiency. Surgical correction of LVOT obstruction and mitral valve repair with elimination of systolic anterior motion were technically successful in all cases. There was no need for mitral valve replacement in all patients. Heart failure NYHA class I-II in early postoperative period was observed in all cases. Careful preoperative planning with a comprehensive analysis of hemodynamic and anatomical features of LV and certain surgical experience are essential for adequate correction of LVOT obstruction without atrioventricular node injury and mitral valve repair.
