Which statement is true about MR management?

• A. Medical therapy alone is sufficient for significant MR
• B. Valve repair or replacement is the definitive treatment for significant MR
• C. Amlodipine cures MR
• D. Observation is always sufficient

Answer: (B)

In significant mitral regurgitation, the definitive way to correct the problem is to surgically repair or replace the mitral valve. Medical therapy can help control symptoms and heart failure, but it cannot fix the leaking valve or stop the progressive volume overload of the left ventricle. Amlodipine does not cure MR; it may modestly influence afterload but it does not address the valve defect. Observation alone is not appropriate for significant MR because, over time, chronic volume overload can lead to marked LV dilation, functional decline, and higher risk of heart failure and arrhythmias. When feasible, valve repair is preferred because it preserves the native valve and usually yields better outcomes than replacement. Replacement is reserved for cases where repair isn’t possible or durable due to the valve’s anatomy or pathology.
