Implication
Supports quantitative MR grading for risk stratification in asymptomatic patients; leaves open whether ERO-guided early surgery improves outcomes.
Structured PICO
Does quantitative grading of mitral regurgitation predict clinical outcomes in patients with asymptomatic mitral regurgitation?
P
Population
Patients with asymptomatic mitral regurgitation
I
Intervention
Quantitative grading of mitral regurgitation (specifically effective regurgitant orifice)
O
Outcome
Clinical outcome
An effective regurgitant orifice of ≥40 mm² in asymptomatic mitral regurgitation is a strong predictor of adverse clinical outcomes, warranting early surgical intervention.
