Mitral valve repair: we must do a better job

Area of Science:

• Cardiology
• Cardiac Surgery
• Medical Mandates

Background:

• Mitral valve repair is the sole cardiac operation capable of restoring expected patient survival.
• A current mandate supports early surgical mitral regurgitation repair before symptom onset or left ventricular dysfunction.

Purpose of the Study:

• To highlight the benefits of mitral valve repair over replacement.
• To emphasize the need for increased mitral valve repair rates in the United States.

Main Methods:

• Review of the natural history of mitral regurgitation.
• Analysis of outcomes comparing mitral valve repair and replacement.
• Assessment of the impact of left ventricular dysfunction and symptoms on survival.

Main Results:

• Mitral valve repair demonstrates superior long-term survival, quality of life, and longevity compared to replacement.
• Medical therapy for mitral regurgitation yields poor results.
• Despite established benefits, mitral valve repair rates in the U.S. remain low.

Conclusions:

• Cardiologists play a pivotal role in increasing mitral valve repair rates.
• Referral to experienced mitral valve repair surgeons is essential.
• Embracing the early repair mandate can significantly improve patient prognosis.
