“…In these models, vascular blood flow is mimicked to simulate the dynamic interaction between the biomaterial and whole blood (Sanak and Wegrzyn, 2010 ). In flat-plate flow chambers, blood flows over a flat piece of biomaterial and in parallel-plate viscometers, blood is filled between two plates made of the biomaterial to be tested and one of the plates is rotated relative to the other (Sukavaneshvar, 2017 ). In Chandler loop, a circular conduit made of the biomaterial or coated with the biomaterial, is filled with fresh human blood with air bubble to allow the blood mixture and rotated in a water bath with 37°C to stimulate blood circulation.…”

“…The generated complement activation products lead to the increased expression of P-selectin, which is an important mediator of neutrophil recruitment and platelet accumulation (Sukavaneshvar, 2017 ). Compared to C3a and C4a, the produced C5a is the most powerful anaphylatoxin.…”

“…The U.S. Food and Drug Administration (FDA) and EU Medical Device Regulatory System are major driving forces behind the trend (44,45). For instance, regions of blood stagnation provide an opportunity for platelets and blood proteins to accumulate to critical concentrations leading to thrombosis (50)(51)(52)(53)(54)(55)(56)(57). A combined experimental and computational approach should be considered to shed light on the flow-mediated mechanisms of thrombosis in bioprosthetic aortic valves.…”

For instance, regions of blood stagnation provide an opportunity for platelets and blood proteins to accumulate to critical concentrations leading to thrombosis (50)(51)(52)(53)(54)(55)(56)(57). Contrary to SAVR where native calcified leaflets are removed from the annulus during open heart surgery, TAVs are implanted within native valves in TAVR procedures.…”

“…Damar yolunun stent yüzeyine tutunan kan pıhtısından ötürü aniden tıkanması şeklinde yaşanan bu süreç son derece tehlikeli olup, birçok zaman ölümle sonuçlanmaktadır. Buna karşın, kaplamasız metalik stent takılmış olan hastalarda, stentin metal yüzeyi vücut tarafından kısa zamanda doğal endotel tabakası ile kaplanmakta, bu nedenle kan sulandırıcı ilaçların sadece birkaç ay kullanılması yeterli olmaktadır [53].…”
