Key result
Left ventricular LGE is not associated with left atrial low voltage areas.
Why the study?
Does the presence of left ventricular late gadolinium enhancement correlate with left atrial low voltage areas in patients with atrial fibrillation?
Observational (n=241)
No
Does the presence of left ventricular late gadolinium enhancement correlate with left atrial low voltage areas in patients with atrial fibrillation?
Absolute Event Rate: 43% vs 33%
p-value: p=0.177
In patients with atrial fibrillation undergoing ablation, left ventricular fibrosis (LV-LGE) is associated with male gender and higher CHA2DS2VASc score but does not correlate with left atrial low voltage areas.
No takes yet. Share an insight, caveat, or question.
LV LGE does not identify LA low-voltage substrate; leaves open independent atrial and ventricular remodeling in AF.
Stegmann et al. (2018) conducted an observational in Atrial fibrillation (n=241). Left ventricular late gadolinium enhancement (LV-LGE) vs. Absence of LV-LGE was evaluated on Presence of left atrial low voltage areas (LVA) (p=0.177). Left ventricular late gadolinium enhancement was not significantly associated with the presence of left atrial low voltage areas (43% vs 33%; P=0.177).
