Xenogenic vs bioprosthetic
1 INTRODUCTION
The use of xenogenic pericardium in cardiovascular surgery and specifically as material for valve repair and reconstruction is not new. Commercially available xenograft patches include bovine, porcine, or equine pericardium and dura mater [39]. Xenograft pericardium tissue patches are superior in blood and tissue compatibility, but are inferior in in vivo durability, mainly due to ...

The life span of bioprosthetic (BP) heart valves limits their application in patients undergoing surgeries for congenital and acquired heart diseases.1–4 Calcification of xenomaterials in BP heart valves is a common underlying cause of symptomatic dysfunction, leading to severe disturbances in intracardiac hemodynamics and the need for reoperation.1,3,5,6 The pathological calcification of ...

overcome this problem and all possible complications of mechanical valves, xenogenic biological prostheses have been developed. The design of bioprosthetic valves purports to mimic the anatomy of the native aortic valve and their flow characteristics are better than mechanical valves, whereas stentless bioprostheses have hemodynamic performance similar to the healthy native aortic valve ...

In patients with a bioprosthetic (tissue) heart valve, DOACs may be used, but this has not been formally studied. DOACS AND OTHER MEDICATIONS: Can an NSAID be taken with DOACs? In general, long-term use of a non-steroidal anti-inflammatory drug (NSAID) combined with a DOAC should be avoided. It is probably safe to combine the use of low dose NSAIDs with a DOAC for short, 3-5 day periods, for ...
