Tissue engineered valves have the potential of being an ideal valve substitute for
transplants, as research shows that mechanical valves carry the risk of thromboembolism.
Unlike mechanical heart valves, tissue engineered valves possess excellent
hemodynamics qualities, and shares the same biomechanical properties that is desired in
native aortic heart valves. However, tissue engineered valves obtained are prone to
structural degradation resulting limited durability when implanted. As such, the effects of
decellularization on the biomechanical property of tissue engineered valves are actively
researched upon. The objective of this project is to characterize the structural and the
biomechanical properties of decellularized aortic heart valves and the aim of this project
is to co-relate the mechanical property of decellularized aortic valves with quantified
amounts of collagen and glycosaminoglycans (GAGs). This study performed seeks to
address the contradictory and inconclusive data that exists in literature and hopes to
determine the relationship between the mechanical property and the biochemical
components that exist within the decellularized heart valves. Heart valves that were
decellularized showed a change in surface morphology, mechanical property such as
Young’s Modulus and Maximum Load, and the amounts of collagen and GAGs. It is
shown that apart from the direct co-relation between the mechanical property and the
amounts of collagen and GAGs present and it is concluded that a synergistic relationship
does exist between collagen and GAGs in heart valves decellularized by Triton X-100.This translates to the closest resemblance of mechanical properties as compared to native
aortic valves, making it the most suitable decelluarizing agent. |
