Hancock II® (HII) Stented Porcine Bioprosthesis (Medtronic)

The HII® is made of a porcine aortic valve fixed in glutaraldehyde and mounted on a low-profile stent comprised of an acetyl homopolymer (Delrin®). This bioprosthesis has a comparatively lower calcification rate than the above options.[28]

The HII® bioprosthesis continues to show good long-term results and durability, especially in patients over 65 years of age.[29] The 20-year actual risk of SVD is 18% ± 3% and 23% ± 3% in all aortic and mitral valve replacement patients, respectively.[30,31]
