Transcatheter Aortic Valve Replacement (TAVR) procedure

It is a minimally invasive procedure to replace a narrowed aortic valve that fails to open properly which may be an option for those who can’t have open-heart surgery.
It is the replacement of the aortic valve of the heart through the blood vessels (as opposed to valve replacement by open heart surgery).
Usually, valve replacement requires an open heart procedure with a “sternotomy”, in which the chest is surgically separated (open) for the procedure.
The TAVR procedures can be done through very small openings that leave all the chest bones in place.
In this procedure, generally, doctors insert a catheter in the patient’s leg or chest and guide it to his/her heart.

The replacement valve is delivered via one of several access methods:

In the upper leg,
Through the wall of the heart, beneath the collar bone,
Through a minimally invasive surgical incision into the aorta,
From a temporary hole in the aorta near the belly button through a vein in the upper leg, etc.
