Combined approach to surgical treatment of hypertrophic obstructive cardiomyopathy (hocm)

The article presents data on evaluation of long-term results of prophylactics of systolic anterior motion (SAM) of the mitral valve (MV) (SAM syndrome) by using edge-to-edge technique (Alfieri technique) without placement of an annuloplasty ring in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: A total of 16 patients aged 18 years and older with clinical signs of left ventricular outflow tract (lVoT) obstruction were included in the study. All patients were randomized into two groups. Group 1 included 7 patients who underwent isolated septal myectomy; group 2 included 9 patients who underwent septal myectomy in a combination with the transaortic edge-to-edge MV repair by Alfieri technique (Alfieri O., 1996). Follow-up examinations were performed immediately after surgery and then at 6, 12, 24, 36, and 72 months after surgery. Results: After surgery, LVOT gradients were 24.95±12.98 mmHg in group 1 and 16.62+13.06 mmHg in group 2 (р
