Abstract
The decellularized heart valve offers potential as an improved heart valve substitute and as a scaffold for the tissue engineered heart valve; however, the consequences of processing must be fully characterized. To date, the effects of decellularization on donor valves from different species have not been evaluated in such a way that permits direct comparison between species. In this manuscript, we report species-dependent variation in the biochemical and biomechanical properties of human and ovine aortic heart valve leaflets following decellularization. This is of clinical significance, as current regulatory guidelines required pre-clinical use of the ovine model to evaluate candidate heart valve substitutes.
