The initial cost for TAVR, along with care before and after the procedure (including both hospital and physician fees), was roughly $78,000, with the commercial cost for the new valve system estimated at about $30,000.
Somewhat similar to a stent placed in an artery, the TAVR approach delivers a fully collapsible replacement valve to the valve site through a catheter. Once the new valve is expanded, it pushes the old valve leaflets out of the way and the tissue in the replacement valve takes over the job of regulating blood flow.
