Key result
CMR-derived maximum AVJ displacement correlates with EF, and early diastolic velocity correlates with e'.
Why the study?
The correlation between cardiac MRI-derived atrioventricular junction motion variables and transthoracic echocardiography measures of diastolic left ventricular function was not established.
Do Cardiac MRI (CMR) correlates of atrioventricular junction motion correlate with transthoracic echocardiography (TTE) measures of diastolic left ventricular function?
Observational (n=50)

Effect estimate: r = 0.604
p-value: p=<0.001
CMR-derived atrioventricular junction motion variables correlate with traditional echocardiographic measures of diastolic function, offering a novel method to assess diastolic function without additional scan time.
No takes yet. Share an insight, caveat, or question.
CMR MVED may enable diastolic assessment without added scan time; leaves open clinical adoption pending prospective validation.
Saba et al. (2013) conducted an observational in Patients undergoing echocardiography and cardiac MRI (n=50). Cardiac MRI (CMR) assessment of AVJ motion vs. Transthoracic echocardiography (TTE) was evaluated on Correlation between CMR-derived maximum longitudinal displacement (MD) and ejection fraction (EF) (r = 0.604, p=<0.001). Maximum displacement of the atrioventricular junction by CMR significantly correlated with ejection fraction (r=0.604, p<0.001), and maximum velocity during early diastole correlated with e'.
