Aortic Valve Disease Behavior

Dr. Harry Aldrich, Medical Director, Echocardiography, EKG and Stress Testing with Miami Cardiac & Vascular Institute, says aortic stenosis is more common than the aortic regurgitation or leaking of the valve. "Stenosis is when the valve becomes tighter, and doesn't open fully. It happens more commonly with age," he highlights. He also explains a normal valve opens about two square centimeters, but one with stenosis is opening about halfway, that is a 50% decrease in the size of the valve as it gets to severe aortic stenosis.
