Abstract:
In 1968, Bentall introduced a composite valve-graft that became the "gold standard" for aortic root replacement. Since then, several alternatives have arisen; one is the Freestyle (Medtronic) stentless aortic root bioprosthesis. This porcine aortic valve has excellent results, and we describe the surgical technique we have developed during our 30-year experience.
