Abstract
A method for deploying an aortic valve prosthesis includes the steps of: making a first opening leading to the left atrium; passing the valve prosthesis through the opening and into a cardiac chamber of the left side of the heart using a first manipulation instrument; making a second opening in the arterial system and advancing one end of a second manipulation instrument through the arterial opening and into the cardiac chamber; securing the second manipulation instrument to the valve prosthesis; and using the second manipulation instrument to retract at least a portion of the valve prosthesis out of the cardiac chamber.
