Transcatheter Aortic Valve Implantation (TAVI) or Transcatheter valve replacement (TAVR) is a procedure that allows a valve to be implanted using a long narrow tube called a catheter.
Usually, the catheter is inserted into a large blood vessel in the groin or through a small incision in the chest also called TAVI.
1)This minimally invasive surgical procedure repairs the valve without removing the old, damaged valve.
2)Somewhat similar to a stent placed in an artery, the TAVI or TAVR approach delivers a fully collapsible replacement valve to the valve site through a catheter.
3)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.
4)The TAVI or TAVR procedure takes 45 to 60 minutes.
5)Going into the room, having the procedure performed and leaving the room takes two to three hours.
6)Usually valve replacement requires an open heart procedure with a “sternotomy.”, in which the chest is surgically separated (open) for the procedure.
7)The TAVR or TAVI procedures can be done through very small openings that leave all the chest bones in place.
It is approved for people with symptomatic aortic stenosis who are considered an intermediate or high risk patient for standard valve replacement surgery.
