Echocardiography is commonly used to time surgery in patients with chronic aortic regurgitation (AR), but cardiac magnetic resonance (CMR) may provide more precise measurements of regurgitation severity and left ventricular (LV) remodeling.
A study of 263 patients compared the outcomes of these imaging methods, finding that CMR better predicted AR-related events and improved statistical models for assessing patient risk.
CMR demonstrated superior reliability and accuracy over echocardiography in evaluating AR severity and its effects on the LV, with specific measurements like regurgitant fraction and LV volumes being strong predictors of patient outcomes.
