- Balloon valvuloplasty—A balloon device is inserted into the blocked mitral valve to open or enlarge the valve. This may provide temporary relief of symptoms. However, the valve may become blocked again.
- Mitral valve replacement—This is the surgical replacement of a defective heart valve. This surgery is usually delayed until symptoms are severe or the patient can no longer be helped by other procedures.
- Treat strep throat infections promptly to avoid rheumatic fever, which can cause scarring of the heart valve. Always finish all of the antibiotics prescribed, even if you feel better before taking all of the doses.
- Get regular medical care, including checkups and periodic electrocardiograms.
- Talk to your dentist and doctor about your condition before any medical or dental procedures. It is no longer recommended that you take antibiotics to prevent infections before dental or medical procedures, but it may be necessary in some cases.
- If your valve problem was caused by rheumatic fever, talk to your doctor about antibiotic treatment to prevent future episodes of rheumatic fever.
