Thanks for that link. I have already viewed all of the Anteris web material and acknowledged the advances the one piece valve imparts. On the animated presentation, the DurAVR valve appears pretty much the same as other valves on the market.
The reduction of calcification is also an improvement despite the dispute over the degree. As I previously posted, my beef is not with these technical improvements, it's with the presentation of them leading viewers to believe DurAVR are the only TAVR valves available and with a placement method they invented.
