Stentless heart valve and holder
First Claim
1. A stentless aortic valve prosthesis comprising an animal aortic segment having an external surface and an internal surface, the aortic segment further comprising an aortic root, an outflow rim adjacent the aortic root, an inflow rim, a left coronary artery, a right coronary artery, a right coronary septal shelf, a plurality of valve leaflets, each valve leaflet having cusps and edges with the adjacent edges of the valve leaflets meeting to form commissures, and a pseudoannulus line located adjacent the commissures along the internal surface of the aortic segment, the improvement comprising:
- coronary openings formed by cutting away the left and right coronary arteries while leaving intact a band of aortic wall adjacent the outflow rim.

Abstract
A stentless aortic heart valve having a disposable holder with a removable handle can be manually reversed by the physician during suturing to provide a relatively unobstructed view into the patient'"'"'s aorta. A covering applied to strategic regions on the exterior and interior of the device provides a firm ground for suturing the prosthetic heart valve into position, and for attaching the detachable holder.
