TRANSAPICAL METHOD OF DELIVERING PROSTHETIC HEART VALVE

摘要

A method of delivering a prosthetic heart valve to the aortic valve annulus while a patient's heart is beating. 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 sheath is passed over the guidewire and into the left ventricle. A prosthetic heart valve is advanced over the guidewire and through the introducer sheath using a delivery catheter. After positioning the prosthetic heart valve in the native aortic valve, the prosthetic heart valve is radially expanded in the aortic valve annulus for replacing the function of the native aortic valve.

1. A method of implanting a prosthetic heart valve in an aortic valve annulus of a patient while the patient's heart remains beating, comprising:
accessing a left ventricle through an intercostal incision; forming a puncture in the left ventricle; introducing a guidewire through the puncture and into the left ventricle; advancing the guidewire through a native aortic valve; passing an introducer sheath over the guidewire and through the puncture into the left ventricle, the introducer sheath having a lumen extending therethrough, the introducer sheath including a proximal housing containing a valve assembly for preventing bleeding from the lumen; inserting a valve delivery device over the guidewire, through the valve assembly and through the lumen of the introducer sheath, the valve delivery device having a prosthetic heart valve mounted thereon; advancing the valve delivery device over the guidewire until the prosthetic heart valve is located in the native aortic valve; and expanding the prosthetic heart valve in the aortic valve annulus for replacing the function of the native aortic valve.
