Key result
Left atrial function assessed by velocity-encoded cardiac magnetic resonance imaging showed wide variability and significantly correlated with left ventricular ejection fraction (r = 0.44).
Why the study?
Can velocity-encoded cardiac magnetic resonance imaging (Ve-CMR) assess left atrial function and identify clinical parameters associated with it in patients referred for CMR?
Observational (n=39)
No

Effect estimate: r = 0.44
p-value: p=<0.01
Velocity-encoded CMR demonstrates wide variability in left atrial function among patients referred for clinical CMR, with significant correlations to LVEF, left atrial volume, and mitral regurgitation severity.
Ve-CMR LA function measures should not change practice; leaves open prospective validation of clinical utility.

Vu et al. (2013) conducted an observational in Referred for cardiac magnetic resonance imaging (n=39). Velocity-encoded cardiac magnetic resonance imaging (Ve-CMR) was evaluated on Correlation between left atrial function and left ventricular ejection fraction (r = 0.44, p=<0.01). Left atrial function assessed by velocity-encoded cardiac magnetic resonance imaging showed wide variability and significantly correlated with left ventricular ejection fraction (r = 0.44).
