Hi ~
You can find out more about this by going under "New Advancements" and then clicking on "Good Morning America". I always watch Good Morning America and they had a segment where they did this procedure successfully on a 92 year old nun. It's a wonderful advancement and will probably be the way they will replace aortic valves many years down the road. Unfortunately, it will not work if your mother should have a bicuspid aortic valve. Also, right now it is done as part of the FDA "Partner Study" and your mother would essentially be a guinea pig. A computer (not a doctor) decides whether you get the percutaneous aortic valve, or not. It's basicially like a flip of a coin as to whether the patient gets it, or not. The computer will decide if she gets it, or traditional surgery. If she is deemed completely inoperable, she would either get the percutaneous aortic valve, a valvuloplasty, or traditional medicine. Also, since a large catheter is needed to thread the valve up to the heart, you need to have extra large arteries for it to work. I know all this since i am deemed inoperable and my doctor referred me to Cleveland Clinic (who also participates in this study), and i was rejected because my valve is bicuspid. They said that even if it should become available for people with bicuspid valves, i would still have to go there for tests to make sure my arteries were large, and that the computer might still decide i couldn't get it. So, there is a long way to go before this will be a viable option for people with severe aortic stenosis who need their valve replaced.
It wouldn't hurt to look into it though. You could go into Columbia-Presbyterian Hospital's website and contact Dr. Martin Leon, or have your mother's doctor contact him and send your mother's medical records to him.
My best wishes and prayers are with your mother,
