Cavalier King Charles Spaniel and Mitral Valve Disease MVD
Mitral Valve Disease (MVD): MVD is a degeneration of the heart’s mitral valve, one of four sets of valves in a Cavalier King Charles Spaniel’s heart. As the mitral valve degenerates, the valve no longer fully closes after each pumping action, allowing some blood to flow backwards through them from the ventricle back into the atrium. As the condition worsens, more and more blood is able to backflow through the valve. In the final stages, the valve’s struts sometimes break, causing the valve to collapse completely. MVD is the most common heart disorder in older dogs of all breeds, affecting more than a third of all dogs over 10 years of age.
