Even though there is great variation among hand cutting instruments, they have certain design features in common. Each hand instrument is composed of three parts: the handle, the shank and the blade. The handle can be small, medium, or large, smooth or serrated.
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.
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.
