Porcine Xenograft Valves
An analysis of 211 patients who had porcine xenograft valve replacements at Henry Ford Hospital between October 1971 and March 1974, was accomplished, with 100% follow-up. The follow-up period extended from 60-89 months after implantation. One hundred sixty-seven patients with 192 valves survived the perioperative period and were subjected to life table analysis. Hemodynamically significant por...
متن کاملXenoantigenicity of porcine decellularized valves
BACKGROUND The xenoantigenicity of porcine bioprosthetic valves is implicated as an etiology leading to calcification and subsequent valve failure. Decellularization of porcine valves theoretically could erase the antigenicity of the tissue leading to more durable prosthetic valves, but the effectiveness of decellularization protocols in regard to completely removing antigens has yet to be veri...
متن کاملDurability of pericardial versus porcine aortic valves.
OBJECTIVES This study compares the long-term performance of the Carpentier-Edwards (CE) porcine bioprosthesis and the CE pericardial bioprosthesis for aortic valve replacement (AVR). BACKGROUND With new bioprostheses on the horizon, there is renewed interest in how the long-term durability of current pericardial bioprostheses compares with the traditional porcine bioprosthesis. METHODS We r...
متن کاملA new storage solution for porcine aortic valves.
The aim of this study was to assess the calcification tendency of two biovalves manufactured by different fixation techniques and compare their biocompatibility when implanted subcutaneously in rats. Two biological valve types (Intact) and Mosaic, stored in either glutaraldehyde or in a solution recently developed in our department, were investigated ultrastructurally and their calcium content ...
متن کاملA nonlinear anisotropic model for porcine aortic heart valves.
The anisotropic property of porcine aortic valve leaflet has potentially significant effects on its mechanical behaviour and the failure mechanisms. However, due to its complex nature, testing and modelling the anisotropic porcine aortic valves remains a continuing challenge to date. This study has developed a nonlinear anisotropic finite element model for porcine heart valves. The model is bas...
