ABSTRACT:
A stentless aortic bioprosthesis having patent, non-ligated coronary artery segments extending therefrom, and methods for surgical replacement of aortic and/or non-aortic (e.g., pulmonary) heart valves with such stentless aortic bioprosthesis. The presence of the patent, non-ligated coronary segments facilitates end to end anastomosis of the patient's native coronary arteries and/or existing coronary artery bypass grafts to the coronary segments of the bioprosthesis even when such native coronary arteries (or coronary grafts) are too short to reach the wall of the aortic segment of the bioprosthesis. The presence of such patent, non-ligated coronary segments also eliminates the need for removal of a "button" or segment of the native aorta in connection with the native coronary artery segments prior to implantation of the bioprosthesis, and is thus advantageous for patients whose ascending aorta is diseased or otherwise compromised.
