An implantable prosthetic heart valve comprising: a valve body, a sewing ring assembly surrounding the valve body and comprising at least a fabric collar and preferably also a stiffening ring, and a tubular vascular graft having a proximal end and a distal end. The proximal end of the graft passes between the fabric collar and the valve body, but not between the stiffening ring and the valve body. The proximal end of the graft is preferably retained by a retaining ring that engages a retaining ring in the downstream end of the fabric sleeve.
