Coronary Perfusion Following a Transcatheter Aortic Valve Replacement in Either Reanimated Swine or Preserved Human Hearts

Pumping New Life into Heart Research: How ViVitro's Superpump is Changing TAVR Studies
In this study, researchers took a unique approach by reanimating swine and human hearts with a ViVitro Superpump to investigate how TAVR implantation affects coronary pressure. Using the Superpump and detailed CT scans, they measured what they call the Estimated Leaflet to Ostium Distance, or ELOD, and found a clear correlation: the shorter that distance, the more coronary pressure could drop. In other words, by getting these hearts beating again in a lab setting, they demonstrated that ELOD might be a better predictor of coronary obstruction risk than some traditional measurements. It’s a solid example of how ViVitro’s technology is helping refine our understanding of heart valve procedures, all without the need for animal or patient trials.
