A method and apparatus for percutaneously implanting an aortic valve prosthesis includes a pump for pumping oxygenated blood from the left atrium into the descending aorta, during a period of time in which an aortic valve prosthesis is being implanted within a diseased aortic valve. First and second catheters are associated with the pump, and a third catheter has an end which is adapted for insertion into the ascending aorta, and the third catheter has an aortic valve prosthesis associated with another end of the third catheter. |
