Advances in soft robotics have led to the development of high-fidelity simulators of pathophysiology for biomedical applications. An MCL was built using a pulsatile pump (SuperPump, ViVitro Labs), an anatomically accurate compliant silicone aortic vessel (E ≈ 1 MPa, United Biologics) connected to two adjustable compliance chambers (that is, ventricular, systemic), and a resistive valve. The models leverage haemodynamic mimicry and may facilitate the development of patient-specific applications. The models could also facilitate the clinical translation of treatments; in particular, a cohort of AS patients could be recapitulated in an in vivo porcine model, and new treatments could be evaluated preclinically.

Conceptually, a tissue engineered heart valve (TEHV) would be especially appealing in the pediatric setting since small size and somatic growth constraints would be alleviated. Here, we utilized porcine small intestinal submucosa (PSIS) for valve replacement... … the Dacron tubes housing the PSIS valves were measured in order to secure the valve‐in‐ conduit (Figure 1) in the mitral position within a pulse duplicator system (ViVitro Labs, Victoria, BC) … A pulse duplicator system… ... Our findings suggest that the altered structural responses of PSIS, post-fatigue, rather than de novo tissue formation, are primarily responsible for the valve’s ability to accommodate somatic growth during the acute phase (90 days) following mitral valve replacement...

Tissue engineered scaffolds have emerged as a promising solution for heart valve replacement because of their potential for regeneration. However, traditional heart valve tissue engineering has relied on resource-intensive, cell-based manufacturing, which increases cost and hinders clinical translation. ...We demonstrated controlled modulation of these scaffold parameters and show initial biocompatibility and functionality in vitro...

Tissue engineering approaches utilizing biomechanically suitable cell-conductive matrixes should extend xenograft heart valve performance, durability, and growth potential to an extent presently attained only by the pulmonary autograft. To test this hypothesis, we developed an acellular, unfixed porcine aortic valve-based construct. The performance of this valve has been evaluated in vitro under simulated aortic conditions, as a pulmonary valve replacement in sheep, and in aortic and pulmonary valve replacement in humans.
