These are images from a TAVR (Trans-catheter Aortic Valve Replacement). This procedure is done for patients who need a heart valve replacement, but are too frail to undergo open heart surgery. The valve [A] fails to open properly, creating a condition known as Aortic Stenosis. This results in insufficient blood flow to the body. The replacement valve [B] is compressed into a small cylindrical shape, and inserted with a catheter, most often through the groin. It is then threaded through the iliac arteries, aorta, and placed inside the diseased valve. A balloon is inflated to open up the new valve and secure it in place over the diseased valve. Figure C shows the size of the valve opening before and after the procedure. The 3DQ Lab is an integral part of the TAVR team. We provide crucial measurements and images to assist in surgical planning. The area just below the valve (Aortic Annulus) is measured to determine the size of the replacement valve, and the Iliac Arteries are measured to determine if the catheter and valve will be able to pass through the vessels. These measurements and others done by the 3DQ Lab Technologists allow the surgeons to screen patients for eligibility, plan the procedure, and assist in placement of the valve during surgery.
