Abstract

Objectives: This retrospective observational study aimed to evaluate the correlation between visually estimated left ventricular ejection fraction (LVEF) via 2D echocardiography (ECHO) and quantitatively measured LVEF via cardiovascular magnetic resonance imaging (CMR).

Methodology: The study was conducted at Aga Khan University Hospital, involving patients who underwent both 2D ECHO and CMR within a maximum interval of three months between the two studies. LVEF was visually estimated by experienced cardiologists on 2D ECHO and quantitatively calculated on CMR.

Results: Among 127 patients meeting inclusion criteria, comparisons between visually estimated LVEF ranges on ECHO and LVEF on CMR consistently showed highly significant differences (p < 0.0001), with ECHO underestimating LVEF. The mean difference between visually estimated average LVEF by ECHO and calculated LVEF by CMR was 4.9 ± 7.0. Subgroup analysis revealed consistent findings across patients with coronary artery disease (CAD) and those with dilated or hypertrophic cardiomyopathy.

Conclusion: Despite a significant difference, the observed discrepancy in LVEF values between visually estimated ECHO and quantitatively measured CMR remains small. Thus, visually estimated LVEF by experienced readers retains its reliability as a method for diagnosing and managing patients in routine clinical practice.
