Key result
CMR-derived early diastolic AVJ velocity correlates moderately with TDE e'.
Why the study?
Mitral annular plane systolic excursion and Doppler mitral annulus velocity are important markers of cardiac function, but practical CMR techniques to measure AVJ motion and correlate with echocardiography are needed.
Does atrioventricular junction motion tracking from cine CMR correlate with tissue Doppler echocardiography e' and ejection fraction?
Cross-Sectional (n=27)
No

Effect estimate: r = 0.624
p-value: p=0.001
Atrioventricular junction motion tracking from cine CMR provides a practical method to assess systolic and diastolic function that correlates moderately with established echocardiographic parameters.

Supports CMR for diastolic assessment; hypothesis-generating and requires larger prospective validation before clinical use.
Saba et al. (2014) reported a cross-sectional. Atrioventricular junction motion tracking from cine CMR vs. Tissue Doppler echocardiography (TDE) was evaluated on Correlation between CMR-derived maximum velocity of the AVJ in early diastole (MVED) and TDE e' (r = 0.624, p=0.001). CMR-derived maximum velocity of the atrioventricular junction in early diastole showed a moderate correlation with tissue Doppler echocardiography e' (r = 0.624, p = 0.001).
