Abstract
A valved conduit including a bioprosthetic aortic heart valve connected to a tubular conduit graft forming an ascending aorta. The conduit graft may attach to the heart valve in a manner that facilitates a redo operation in which the valve is replaced with another valve. A sewing ring may be pre-attached to the inflow end of the graft, and then the valve connected to a delivery holder advanced into the graft and secured to the sewing ring. Dry bioprosthetic valves coupled with conduit grafts sealed with a bioresorbable medium can be stored with the delivery holder.
