Team Takes Important Step in Better Understanding Calcific Aortic Valve Disease

Researchers at the University of Wisconsin–Madison say they have teased apart, for the first time, the early cascade of events that may eventually cause stenosis, a severe narrowing of the aortic valve that reduces blood flow to body tissues and weakens the heart. The only current treatment for stenosis is valve replacement, which typically requires risky and expensive open-heart surgery."For a long time, people thought calcific aortic valve disease (CAVD) was just the valvular equivalent
