METHOD OF SURGICAL TREATMENT OF MYOCARDIAL INSUFFICIENCY OF THE LEFT VENTRICLE Russian patent published in 2018 - IPC A61B17/00 A61N1/368 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to cardiovascular surgery. Perform implantation of the ventricular and atrial electrode. Determine the thresholds of stimulation with the help of an external pacemaker with the detection of acute endocardial threshold values. Temporary endocardial electrode is inserted into the right ventricle beforehand, and the ventricular and atrial electrodes are implanted into the left chambers of the heart through the oval window or the atrium of the interatrial septum. Then the electrotype stilettos are successively extracted, the ventricle electrode in the lower third is attached to the spiral shape, and the atrial stiletto is attached to a curved or wavy form, followed by their introduction into the corresponding electrode. Sharp threshold, equal to or less than 0.2 mA, is detected on the endocardium, the electrode heads in these areas are fixed, while the temporary endocardial electrode is activated until the ventricular and atrial electrodes are installed.

EFFECT: method allows to increase the effectiveness of treatment as a result of normalization of the left ventricular outflow tract, decrease of the gradient, improvement of the contractile function and blood supply of the myocardium, which improves the quality and duration of their life of this category of patients.
