Since you know a bit, can you clarify something not clear from the article? My aortic valve was replaced due to "ectasia", meaning the valve root stretched so the leaflets, which were otherwise fine, no longer met properly. Given the type of reconstruction to fit a porcine tissue replacement then, does this make TAVR more, or less, indicated for the replacement?

One problem with a TAVR in patients with aortic valve regurgitation is that they don’t have enough calcification on their valve in contrast to aortic valve stenosis patients. Some valves need the calcifications to stay in place. As far as I know there are some studies with TAVR in regurgitation patients but it’s not standard

Less, it’s not on label for aortic regurgitation, only aortic stenosis.
