- Cardiomyopathies—Diseases that weaken the heart muscle and stretch the mitral valve.
- A history of rheumatic fever or other serious infectious disease
- Autoimmune diseases, such as systemic lupus erythematosus and rheumatoid arthritis
- Storage diseases such as hemochromatosis and glycogen storage disease
- Cardiovascular disease
