Replacing the diseased aortic valve and the proximal aorta in the elderly patient.

Subcoronary implantation of the Medtronic stentless bioprosthesis and an extension using a vascular tube prosthesis provide a safer alternative to the more invasive conventional composite graft replacement or a full root replacement using a homograft or a stentless valve. The advantage lies in eliminating the need for coronary mobilisation and anastomosis which actually lead to the increased risk in those procedures.
