Key result
Cardiovascular magnetic resonance for quantitative assessment of atrioventricular junction velocities correlated strongly with tissue Doppler echocardiography (r=0.691-0.835, p<0.001).
Why the study?
Does cardiovascular magnetic resonance (CMR) accurately quantify atrioventricular junction (AVJ) velocity compared to tissue Doppler echocardiography in patients with and without cardiac disease?
Observational (n=145)
Does cardiovascular magnetic resonance (CMR) accurately quantify atrioventricular junction (AVJ) velocity compared to tissue Doppler echocardiography in patients with and without cardiac disease?
Effect estimate: r = 0.691-0.835
p-value: p=<0.001
CMR-derived AVJ velocity assessment is feasible, accurate, and highly reproducible compared to tissue Doppler echocardiography for evaluating systolic and diastolic cardiac function.

Supports CMR for AVJ velocity assessment; leaves open whether it improves outcomes over echocardiography in practice.
Leng et al. (2015) conducted an observational in Cardiac dysfunction (heart failure, hypertrophic cardiomyopathy, myocardial infarction, repaired Tetralogy of Fallot) (n=145). Cardiovascular magnetic resonance (CMR) vs. Tissue Doppler echocardiography (TDE) was evaluated on Correlation of CMR-derived septal and lateral AVJ velocities with TDE measurements (r = 0.691-0.835, p=<0.001). Cardiovascular magnetic resonance for quantitative assessment of atrioventricular junction velocities correlated strongly with tissue Doppler echocardiography (r=0.691-0.835, p<0.001).
