Mitral valve stenosis is less common today than it was several decades ago because the most common cause, rheumatic fever, is rare in the United States. However, rheumatic fever remains a frequent problem in countries where antibiotic use isn't as common.

Risk factors for mitral valve stenosis include a history of rheumatic fever and recurrent strep infections. Radiation treatment involving the chest can result in mitral valve stenosis. Other unusual causes of mitral valve stenosis include medications, such as ergot preparations used for migraines.
