Designing a stentless valve conduit for use in a biological Bentall procedure.

ABSTRACT

Various modifications of the Bentall procedure have been described using mechanical valve conduits. A further modification, using a bioprosthetic valve, has grown in popularity as this prevents the need for lifelong anticoagulation. Additional innovation using a stentless bioprosthetic valve has the theoretical advantages of allowing for a larger bioprosthesis and an improved durability. The technical aspects involved in designing a stentless valve conduit for use in a biological Bentall procedure are described.
