The aim: Assessment of a surgical treatment modality for patients with an obstructive hypertrophic cardiomyopathy.

Materials and methods: From 2013 to 2014 year cardiac surgery department of National Scientific Medical Center (Astana, Kazakhstan) performed 14 procedures for correction of an obstructive cardiomyopathy. Morrow procedure in isolated form or in combination with correction of other cardiac pathology had been utilized.  Isolated form of Morrow procedure was used in 3 patients (21.4%), in other 11 cases in combination with coronary artery bypass surgery (CABG) – 3 (21,4%); CABG with mitral valve repair – 6 (42,8%); David procedure – 1 and a section of the myocardium muscular bridge – 1  case.

Results: early and long-term results of surgical correction of an obstructive cardiomyopathy are presented. The average pressure gradient was 13.9 + 6 mm Hg (prior to operation of 79.7+61.3 mm Hg). Average thickness of the interventricular septum after myomectomy was 13,7 + 3,3 mm (prior to surgery 23.1+3.2 mm). In cases when correction of valve pathology was performed simultaneously, function of valves by echocardiographic control was also estimated (size of gradient and regurgitation). Satisfactory clinical results were obtained in 12 patients. Two patients died in early postoperative period.

Conclusions: we recommend expanded myomectomy techniques, as opposed to classical Morow procedure. Our department experience with these procedures shows that this approach leads to considerable clinical improvements in the patients with obstruction of the left ventricular outflow tract.
