Key result
Cardiovascular magnetic resonance quantification of aortic regurgitation identified 85% of patients with regurgitant fraction >33% who needed surgery, compared to 8% with ≤33%.
Why the study?
Does cardiovascular magnetic resonance quantification of aortic regurgitation predict the future need for surgery in asymptomatic patients with moderate or severe AR?

CMR regurgitant fraction >33% was associated with progression to surgery in asymptomatic AR; leaves open whether quantification should refine guideline thresholds.
Does cardiovascular magnetic resonance quantification of aortic regurgitation predict the future need for surgery in asymptomatic patients with moderate or severe AR?
CMR-quantified aortic regurgitant fraction >33% is highly predictive of progression to symptoms or the need for surgery in asymptomatic patients with moderate-to-severe aortic regurgitation.
Myerson et al. (2012) studied this question. Cardiovascular magnetic resonance quantification of aortic regurgitation identified 85% of patients with regurgitant fraction >33% who needed surgery, compared to 8% with ≤33%.
