Key result
Speckle tracking echocardiography parameters, including PALS (r=-0.54, P<0.001) and LA stiffness index (r=0.65, P<0.001), significantly correlated with LA fibrosis extent on electroanatomical mapping.
Why the study?
Do speckle tracking echocardiography parameters and serum biomarkers correlate with electroanatomical mapping-derived left atrial fibrosis in patients with nonvalvular atrial fibrillation?
Observational (n=66)
Do speckle tracking echocardiography parameters and serum biomarkers correlate with electroanatomical mapping-derived left atrial fibrosis in patients with nonvalvular atrial fibrillation?
p-value: p=<.001
Speckle tracking echocardiography parameters, specifically PALS and LA stiffness index, correlate well with invasive electroanatomical mapping of left atrial fibrosis, offering a noninvasive tool for patient selection prior to ablation.
No takes yet. Share an insight, caveat, or question.
Speckle tracking parameters were associated with LA fibrosis; hypothesis-generating for noninvasive assessment before AF ablation.
Pilichowska‐Paszkiet et al. (2018) conducted an observational in Nonvalvular atrial fibrillation (n=66). Speckle tracking echocardiography (STE) and biomarkers was evaluated on Correlation between LA echocardiographic parameters/biomarkers and LA fibrosis derived from electroanatomical mapping (LAPA) (p=<.001). Speckle tracking echocardiography parameters, including PALS (r=-0.54, P<0.001) and LA stiffness index (r=0.65, P<0.001), significantly correlated with LA fibrosis extent on electroanatomical mapping.
