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.
Currently, this is an option for patients with severe aortic stenosis causing symptoms that are too high risk for standard valve replacement surgery. During a TAVI or TAVR procedure, a catheter about the size of a pen, is inserted in the artery in the leg and carefully passed up into the heart. One type of TAVR valve, made of bovine (cow) tissue and supported on a metal stent, is then implanted inside the narrowed valve resulting in a normal functioning aortic valve. With a TAVR procedure, the patient does not need the chest opened for surgery or put on a heart-lung (bypass) machine.
