Mitral Regurgitation
A condition where the mitral valve doesn't close tightly, causing blood to flow backward into the left atrium when the heart contracts. Can be primary (valve problem) or secondary (heart enlargement). Leads to heart enlargement and heart failure if severe.

Risk Factors
Diagnostic Methods
- 1Echocardiogram
- 2Transesophageal echocardiogram
- 3Cardiac MRI
- 4Cardiac catheterization
- 5Chest X-ray
- 6ECG
- 7Physical exam (holosystolic murmur)
Prognosis
Good with proper treatment. 10-year survival >80% after surgery. Untreated severe MR has poor prognosis (5-year survival 50-60%). Early intervention improves outcomes significantly.
Prevention
- Rheumatic fever prevention
- Endocarditis prophylaxis
- Blood pressure control
- Prompt treatment of strep infections
- Regular cardiac monitoring (if valve disease known)
Research Status
Surgical mitral valve repair preferred over replacement. Transcatheter edge-to-edge repair (MitraClip) for high-risk patients. Medications for heart failure symptoms. Early surgery recommended before left ventricle dysfunction develops.
