The transcatheter aortic valve replacement (TAVR) procedure takes about 3-4 hours to complete. You will be under general anesthesia for the entire procedure and when you wake up you will be in our Cardiac Surgical Intensive Care Unit. The nurses will quickly get you out of bed and physical therapy will be started.AVR is a minimally invasive procedure performed without the need for a heart and lung machine under general anesthesia. A small (3-5 inch) incision (opening) is created in the upper leg through which the new aortic valve is placed.
