I read the article with great excitement and enthusiasm. The idea of contact-less rotor and dynamic positioning is IMO brilliant. However when I read the overview article on Wikipedia, my optimism was somewhat damped. Even the "ancient" model Jarvik-5 could a help a calf survive for 286 days, so the 90 days bovine-testing does not say much. Other prototypes had achieved even greater success in human trial but were later abandoned like the AbioCor design. OHSU has developed a simple design with contact-less shuttling pump similar to the concept of Bivacor but seem failed for clinical trial. Other design like the Carmat, the Polish POLVAD or the Taiwanese Phoenix-7 seem very promising too, but they obviously didn't make any breakthrough yet. AFAIK the bio-compatibility and the stability of the artificial heart are the most important factors. As auch, I think we're still years away when not decades away from a real breakthrough in artificial heart. https://en.wikipedia.org/wiki/Artificial_heart https://en.wikipedia.org/wiki/Artificial_heart
