Structural Valve Deterioration Under the Lens: Insight into Heart Valve Durability and Calcification This study showcases some truly remarkable transformations in both surgical and transcatheter heart valves, all achieved in a controlled lab environment using our ViVitro AWT systems and a Pulse Duplicator. Over a 157 million cycle durability test, these valves were exposed to conditions that mimic years of loading while calcification occurs, allowing us to observe how calcium deposits impact structural valve deterioration. The findings are truly eye-opening. The study not only demonstrated how different valve designs and tissue types respond to calcification but also highlighted that our 1st gen HiCycle system, while solid and reliable, has paved the way for the even more advanced features of our current 3rd gen AWT systems. Imagine how much more we could uncover now with independent valve environments and continuous monitoring! We were especially impressed by the visual content—like Video 8 in the paper, which offers a side-by-side view of control versus calcified valves, a feature reminiscent of our latest Valve Comparison Tool. Ultimately, this research is a great testament to how ViVitro’s products are helping advance medical device testing in a way that reduces the need for animal and patient trials.
