Key result
Although echocardiography-derived LVEF and global longitudinal strain showed good statistical agreement with cardiac magnetic resonance, wide limits of agreement indicate these imaging modalities are complementary rather than clinically interchangeable.

Echocardiographic LVEF, global longitudinal strain, and cardiac magnetic resonance offer synergistic and complementary information for a comprehensive assessment of left ventricular function.

Marly Uellendahl (2026) conducted an editorial in Left ventricular function assessment. Echocardiography (LVEF and GLS) and Cardiac Magnetic Resonance was evaluated on Agreement between LVEF by Simpson's method, GLS, and CMR. Although echocardiography-derived LVEF and global longitudinal strain showed good statistical agreement with cardiac magnetic resonance, wide limits of agreement indicate these imaging modalities are complementary rather than clinically interchangeable.
