Video - Valvular heart disease: Pathology review

Valvular heart disease refers to a group of conditions that affect the heart's valves. The valves within the heart include the mitral, aortic, tricuspid, and pulmonary valves. Some examples of valvular heart disease include aortic stenosis, which is the narrowing of the aortic valve; aortic regurgitation in which blood leaks back through the aortic valve; mitral regurgitation in which there is a narrowing of the mitral valve; mitral stenosis characterized by blood leaking back through the mitral valve tricuspid regurgitation in which blood leaks back through the tricuspid valve; pulmonary stenosis that's characterized by the narrowing of the pulmonary valve; and finally; pulmonary regurgitation in which blood leaks back through the pulmonary valve.
