What causes mitral valve problems?
Mitral valve problems are rarely caused by a birth defect, otherwise known as a congenital condition
More often, simple “wear and tear” may cause part of the valve mechanism to fail. This is called “degenerative disease”. This may be related to advancing age, although many young people will have this condition as well.
Rheumatic fever may damage the mitral valve causing stenosis or regurgitation. Occasionally the mitral valve is damaged by infection or bacterial endocarditis. Ischemic heart disease (coronary artery disease) can also cause the mitral valve to leak.
