The invention concerns a method for managing a cardiac pump (13) intended to assist the heart of a patient, said cardiac pump (13) being intended to send pressurised blood at a flow rate proportional to the speed of rotation V rpm of said pump (13) through the aortic valve of said heart. The invention involves carrying out the following steps, during a same ventricular systole: (a) detecting the closing of the mitral valve of said heart, the speed of rotation V rpm of the pump (13) being strictly less than a maximum value V rpm max of the speed of rotation of said pump (13), (b) increasing the speed of rotation V rpm of said pump (13) such that, at a time t 2 , after the time t corresponding to the closing of the mitral valve, the speed of rotation of the pump (13) is equal, or substantially equal, to said maximum value V rpm max of the speed of rotation, (c) keeping the speed of rotation V rpm of the pump (13) at this maximum value V rpm max for at least a portion of the time period T during which the aortic valve is open, and - optionally repeating steps (a) to (c) for at least the ventricular systole of a next cardiac cycle. |
