Is percutaneous aortic valve replacement being done for regurgitation?

I believe it is being done for stenosis. What about regurgitation. If not, is it expected that this procedure will be used for regurgitation in the near future?

Cleveland Clinic link - I think the proceedures are a long way from replacing standard OHS

Offhand, I'd expect it to be MORE appropriate for prolapse/regurg than for stenosis. In the former case, you might be starting with a full-sized opening, while something's got to be done to fix the stenosis (stent it, "ream it out"?) before a new valve will solve the problem. (You don't normally fix a constriction in a tube by slipping something inside it!)

Not to highjack this, just a note, some companies are specifically tageting replacing their own tissue valves this way (that wear out over time), which is easier as they know exactly what is in their valve.

As I understand the proceedure a balloon is used to crush the old valve and make the opening wider then the new valve is expanded and deployed. I also read in one of Adam Picks news letters that it is being tested for those who already have a tissue replacement that is failing.
