Key result
Cardiac Magnetic Resonance yielded significantly larger left ventricular end-diastolic volumes than 2D and 3D echocardiography in patients with significant primary mitral regurgitation (p<0.001).
Why the study?
Detection of the deleterious effect of MR on the LV is crucial in guiding surgical decisions, prompting a comprehensive LV assessment using 2D echo, 3D echo, and CMR.
How do 2D echocardiography, 3D echocardiography, and CMR compare in the assessment of left ventricular volumes and function in patients with significant primary mitral regurgitation?

How do 2D echocardiography, 3D echocardiography, and CMR compare in the assessment of left ventricular volumes and function in patients with significant primary mitral regurgitation?
CMR yields significantly larger left ventricular volume measurements compared to echocardiography in patients with significant primary mitral regurgitation, highlighting the importance of imaging modality choice in guiding surgical decisions.
Background: Detection of the deleterious effect of MR on LV is crucial in guiding the surgical decision.Aim of the study: Comprehensive assessment of LV with significant primary MR using (2D, 3D echo and CMR).Methods: 40 patients with significant MR have been recruited in a prospective study. Patients underwent 2D and 3D echo and CMR studies. LV volumes, function and GLS were calculated.Results: End diastolic and systolic volumes were significantly larger when measured by CMR (all p < 0.001). EDV measures were strongly correlated with CMR and 3D echocardiography.Conclusion: It’s important to identify early deleterious LV changes.

A 2023 study conducted an observational in Significant primary mitral regurgitation (n=40). Cardiac Magnetic Resonance (CMR) vs. 2D and 3D echocardiography was evaluated on Left ventricular end-diastolic volume (EDV) (p=<0.001). Cardiac Magnetic Resonance yielded significantly larger left ventricular end-diastolic volumes than 2D and 3D echocardiography in patients with significant primary mitral regurgitation (p<0.001).
