valve

has anyone ever heard of an aorta(not aortic) valve replacement?

I'd bet more money than I could afford to lose that this is the same thing, a misspelling or misuse of the word.  

The aorta is a big tube carrying blood from the heart, all around the body.  

Blood comes into your heart from your lungs, with a fresh supply of oxygen.  It leaves your heart through the left ventricle, into the aorta to begin its journey around the body.  

The aortic valve sits there between the left ventricle and the base of the aorta to keep blood that has been pushed into the aorta by the left ventricle from going back into the heart.  

The aorta is not a valve.  The aorta has no other valves attached to it or working with it except the aortic valve.  So the "aorta valve" must be just a mistake in saying "aortic valve."  

So, did anyone take that bet?
