Key Points
- To review diagnostic strategies, clinical guidelines, and management recommendations for patients presenting with chronic mitral regurgitation.
- Evaluated current clinical guidelines and diagnostic protocols using an illustrative clinical case of an asymptomatic 56-year-old male with moderate regurgitation and mild left ventricular enlargement.
- Assessed population-level epidemiology, differentiating physiologic valve leakage from clinically meaningful mitral-valve disease and surgical intervention rates.
- Identified echocardiography as the definitive modality to distinguish benign physiological regurgitation (present in up to 80% of adults) from pathological left ventricular remodeling.
- Outlined clinical decision pathways establishing when watchful surveillance versus timely mitral-valve repair or replacement is indicated in asymptomatic and symptomatic presentations.
