Abstract
A method of delivering a prosthetic heart valve to the aortic valve annulus while a patient's heart is beating is disclosed. The method includes accessing the left ventricle through an intercostal incision and forming a puncture in the left ventricle. A guidewire is advanced into the left ventricle and through the native aortic valve. An introducer is passed over the guidewire and into the left ventricle. A valve delivery device is advanced over the guidewire and through the introducer until a prosthetic heart valve positioned thereon is located within the native aortic valve. The prosthetic heart valve is then radially expanded within the aortic valve annulus for replacing the function of the native aortic valve.
