METHOD FOR OPTIMIZING TREATMENT OF HEART FAILURE IN PATIENTS WITH IMPLANTED ARTIFICIAL LEFT VENTRICLE Russian patent published in 2025 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to cardiology. An echocardiographic examination (EchoCG) is carried out to determine: positions of interventricular septum (IVS), mitral regurgitation (MR) and tricuspid regurgitation (TR), additionally, right heart catheterization (RHC) is performed to assess: pulmonary artery wedging pressure (PAWP), central venous pressure (CVP), cardiac index (CI) and the analysis results are used to select the optimal therapy. If there is no left ventricular discharge: PAWP > 18 mm Hg, CVP < 12 mm Hg, CI 1.8-2.2, IVS is deviated to the right, MR 2 deg. and higher output of artificial left ventricle is increased by 100 rpm with repeated assessment of the same parameters after increase. In case of volume overload of both ventricles: PAWP > 18 mm Hg, CVP > 12 mm Hg, CI 1.8-2.5, IVS occupies any position, the treatment is aimed at reducing the volume of fluid in the vascular bed. In right ventricular failure: PAWP < 18 mm Hg, CVP > 12 mm Hg, CI 1.8-2.2, IVS is deviated to the left, severe tricuspid regurgitation (TR), the output of the artificial left ventricle is reduced by 100 rpm with repeated evaluation of the EchoCG and RHC values with the introduction or intensification of the inotropic therapy. If PAWP < 18 mm Hg, CVP < 12 mm Hg, CI ≥ 2.2, IVS occupies a middle position, MR and TR are 1-2 deg., the target dimensions of the RV, no correction is required.

EFFECT: method enables optimizing the performance of the artificial left ventricle in accordance with the individual’s body parameters, which enable to select the performance parameters of the artificial left ventricle in a personalized manner, which in turn enables to achieve the best result of the operation.
