METHOD FOR BIVENTRICULAR MECHANICAL CIRCULATORY SUPPORT OF HEART DURING PERIPHERAL VENO-ARTERIAL MEMBRANE OXYGENATION Russian patent published in 2024 - IPC A61M25/01 

FIELD: medicine.

SUBSTANCE: invention relates to resuscitation, intensive care, cardiovascular surgery, transplantology and endovascular surgery. In the X-ray operating environment, after the ECHO-cardiography, coronary angiography, the left and right common femoral artery and the left or right common femoral vein are punctured according to Seldinger and introducer 6F is installed. Under the X-ray image, J-shaped conductor 260 cm is brought through the venous introducer, along which the diagnostic catheter Jatkins Right (JR) 5F is introduced into the left or right branch of the pulmonary artery, along which a super-rigid guidewire is introduced, after which the diagnostic catheter and introducer are removed. A venous multistage cannula 21–24F is introduced along the super-rigid guidewire and placed in the position of the pulmonary trunk. Through arterial introducer 6F, conductor 0.035 inch 260 cm is brought into the left ventricular cavity, the introducer is replaced with a drainage catheter with an internal lumen of 8F–10F and connected through a Y-connector with a venous cannula to the supply circuit of the ECMO. On the contralateral side, the arterial introducer is replaced with a venous cannula ECMO 15–17F with a total length of 64.8 cm. Then, an extracorporeal membrane oxygenation is performed.

EFFECT: use of the invention provides a stage of unloading the left ventricle without using the Impella mechanical circulatory support device, reduces risks of complications associated with damage of aortic valve, reduces risks of "Arlekino's syndrome", eliminates necessity of additional antegrade perfusion of arteries of lower extremities.
