Aortic valve bypass

I have not heard of this before, but with the combined knowledge of everyone in the VR forum I'm sure somebody with pipe in real soon. If they by-pass a bad aortic valve, where do they get the material from and where do they place it? Still in the heart?

I have never heard of that either, and I am not sure even how that would work.
Actually it is an old surgery. It was first done in 1960. It was tech. difficult and was soon replaced with what is now traditional AVR. This is done by cuting a hole in the apex of the heart and a graft simular to a regular bypass has a valve place in it and is re attached below the decending aorta. It is starting to be done again as a good choice for those to weak for OHS. Any size or type of valve can be used. It will carry about 2/3 of the blood and the rest continues to go though the orginal valve. It can be done minimal invasive and off pump. Has a lower risk of stroke, and about very thing else.
If you look at the whats new threads I put a link to a site about it. There is a company that makes a kit that makes placing the one end in the heart uch simpler. So it is really an old surgery that is new again. Even though it was done on older and weaker patcients there are some still going 25 years later.

John,
By the time you need another replacement, there's no telling what will be on the market.
I assume, John, you are talking about the Percutaneous procedure which is still limited at this time to the vulnerable patients who cannot undergo OHS. It may become more common in the future. Do not worry about tomorrow. Good luck.
Here is some info about the Percutaneous procedure from Cleveland Clinic:
Percutaneous aortic valve replacement (AVR) is a new treatment being investigated for select patients with severe symptomatic aortic stenosis (narrowing of the aortic valve opening). Research at Cleveland Clinic is evaluating a percutaneous technique for implanting a prosthetic valve inside the diseased calcific aortic valve. The procedure is performed in the catheterization lab.
During the procedure a catheter is placed through the femoral artery (in the groin) and guided into the chambers of the heart. A compressed tissue heart valve is placed on the balloon-mounted catheter and is positioned directly over the diseased aortic valve. Once in position, the balloon is inflated to secure the valve in place.

Nope that is a completely different surgery for those 2 weak to have OHS. The bypass literally has a new valve in a bypass graft and leaves the old one in place.
The one you refer to is a cathater based valve where the baloon mushes the old valve and a new one is implanted. The jury is still out on that one. my fear is that the opening will close much like other baloon proceedures. The bypass valve replacement already has a proven track record.

Interesting! I have not heard to this and would like to learn more about it. 50 years ago the doctor who recommended antibiotics for stomach ulcer was laughed at, nowadays this is the most acceptable medicine. I wonder if we are smarter now than those 50 or 60 years ago or we have more means to prove the effectiveness of those two remedies.

John,
I'm putting the link here in addition to the link you supplied in the New Advancement forum. Thanks!
