Ann: DurAVR First in Human Study 12 Month Results, page-11

I agree Stezza,

6. The 6-minute walk test distance (6MWTD) measuring patient exercise capacity after aortic
valve replacement improved by 32% from baseline, with a 17% improvement from the 30-day
result at 12 months.

If I read this correctly, 83% of the improvement in exercise tolerance occurred after 30 days and the remaining 17% over the following 11 months.
That is more like 21% improvement experienced over the 11 months (17%) relative to that achieved over the first 30 days (83%) compared to baseline.......not a lot of difference between 17 and 21, but it shows considerable ongoing improvement.
