Key result
Cardiac magnetic resonance imaging accurately and reproducibly quantifies mitral regurgitation without regard to regurgitant jet morphology or the need for intravenous contrast.
Why the study?
Accurate quantification of regurgitant volume is a central component to the management of mitral regurgitation.

“By using more cardiac magnetic resonance in patients with mitral regurgitation, cardiologists are able to better understand the extent of the lesion and determine the most appropriate treatment approach. For some patients, that may be the difference between having surgery to correct the valve or not.”
“Many patients don't understand that cardiac imaging is not the same everywhere — for instance, a cardiac MRI performed at a center that doesn't have updated technology, skilled technicians and an expert reading the images may provide an incomplete or inaccurate assessment of heart problems. Patients should seek out a facility that provides high-quality imaging particularly if there are important management decisions to be made.”
CMR provides an accurate and reproducible method for quantifying mitral regurgitant volume, independent of jet morphology.
Accurate quantification of regurgitant volume is a central component to the management of mitral regurgitation. Cardiac magnetic resonance imaging (CMR) accurately quantifies mitral regurgitation as the difference between left ventricular stroke volume and forward stroke volume using steady state free precession and phase contrast imaging. The CMR measurement of mitral regurgitant volume is reproducible and can quantify mitral regurgitation in patients without regard to regurgitant jet morphology, such as patients with multiple and eccentric jets. It can be used to quantify regurgitant volume in patients with multiple valve lesions and concomitant intracardiac shunts without the use of intravenous contrast. Studies have highlighted the accuracy and reproducibility of CMR in quantifying mitral regurgitation and have begun to link CMR to clinical outcomes.
