METHOD FOR SURGICAL TREATMENT OF HYPERTROPHIC OBSTRUCTIVE CARDIOMYOPATHY Russian patent published in 2017 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: esophageal echocardiography is performed. After incision of the ascending aorta, three needles are introduced into the region of the hypertrophied tissue. One needle is inserted under the middle part of the right coronary leaflet. The second needle is inserted under the commissure between the right and left coronary leaflets of the aortic valve. The third needle is set between the two previous ones. Needles are removed into the cavity of the left ventricle, 2-4 mm from the fibrous aortic valve ring, and then the needles are stabilized by Kocher's clamps. The hypertrophied tissue is excised by one block along the three needles from the aortic valve ring towards the top of the left ventricle.

EFFECT: method allows to increase the efficiency of treatment of this category of patients as a result of normalization of the left ventricle output tract, to lower the gradient, to improve the contractile function and blood supply of the myocardium, to improve quality and life expectancy.
