Once the catheter is positioned in the opening of the aortic valve it releases the bioprosthesis at the mid part of the aortic valve.
(Percutaneous Aortic Valve Replacement, NCI Thesaurus)
The researchers teased apart, for the first time, the early cascade of events that may eventually cause stenosis, a severe narrowing of the aortic valve that reduces blood flow to body tissues and weakens the heart.

A bioprosthesis is advanced through the vessels with a catheter up to the diseased native aortic valve.
(Percutaneous Aortic Valve Replacement, NCI Thesaurus)
This multi-stage process may explain why 25 percent of adults over the age of 65 have CAVD with partially blocked aortic valves, but only one percent goes on to develop stenosis due to a valve that can no longer open and close properly.
