Evaluation of pliable bioresorbable, elastomeric aortic valve prostheses in sheep during 12 months post implantation [PDF]
Communications Biology, 2023 Pliable microfibrous, bioresorbable elastomeric heart valve prostheses are investigated in search of sustainable heart valve replacement. These cell-free implants recruit cells and trigger tissue formation on the valves in situ. Our aim is to investigate

Hemodynamic Evaluation of Heart Valve Prostheses
Journal of the American College of Cardiology, 2009 The treatment of aortic valve disease is undergoing rapid changes. In addition to conventional valve replacement that has evolved as the gold standard over several decades, transcatheter techniques have been introduced into clinical practice.

Fifteen years of experience with ATS mechanical heart valve prostheses [PDF]
The Journal of Thoracic and Cardiovascular Surgery, 2009 ATS Medical, Inc, developed a mechanical heart valve that has been in use since 1992. In this article, we present the results of 15 years of follow-up of patients who have undergone ATS heart valve replacement at our hospital.We performed ATS heart valve replacements on 231 patients between September 1993 and March 2008.

Fluid dynamic characterization of a polymeric heart valve prototype (Poli-Valve) tested under continuous and pulsatile flow conditions. [PDF]
, 2015 PURPOSE: Only mechanical and biological heart valve prostheses are currently commercially available. The former show longer durability but require anticoagulant therapy; the latter display better fluid dynamic behavior but do not have adequate durability.
