Aortic Valve Replacement with a Stentless Bioprosthetic Valve: Porcine or Pericardial T2 Cardiac Surgery in the Adult, 4e YR 2012 FD 2012 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-163310-9 LK accesssurgery.mhmedical.com/content.aspx?aid=55920842 RD 2024/10/10 AB The history of stentless xenograft aortic valves follows in the footsteps of the aortic homograft, which was considered historically as the best biologic prosthesis for management of root pathology and for optimizing hemodynamics in the absence of root pathology. The original concept behind creating a stentless xenograft valve was to maintain the excellent hemodynamics of the homograft, while improving on the availability, durability, technical complexity, and costs associated with homografts.
