A method and apparatus for treatment of heart failure by reducing LV diastolic volume and pressure by pumping blood out of the LV during diastole. A pump is synchronized to the heart cycle, connected to the apex of the LV and discharging into the right atrium of the heart. A left ventricle to aorta one-way valved conduit with added compliance decreases blood pressure in the aorta and the resistance to the ejection of blood by the heart decreases the energy requirements of the heart. |
