<unk>  is any cardiovascular disease process involving one or more of the four valves of the<unk>  (the aortic and mitral valves on the left side of<unk>  and the pulmonic and tricuspid valves on the right side of<unk> . These conditions occur largely as a consequence of aging, but may also be the result of congenital (inborn) abnormalities or specific disease or physiologic processes including rheumatic<unk>  disease and pregnancy. Anatomically, the valves are part of the dense connective tissue of the<unk>  known as the cardiac skeleton and are responsible for the regulation of blood flow through the<unk>  and great vessels. Valve failure or dysfunction can result in diminished<unk>  functionality, though the particular consequences are dependent on the type and severity of<unk>  disease. Treatment of damaged valves may involve medication alone, but often involves surgical valve repair or valve replacement.
