Correlations between left atrial strain and left atrial pressures values in patients undergoing atrial fibrillation ablation
Why the study?
The study was conducted to investigate correlations between left atrial strain assessed by speckle tracking echocardiography and directly measured left atrial pressure values, and to characterize patients with lower left atrial strain.
Does left atrial strain assessed by echocardiography correlate with directly measured left atrial pressures in patients with atrial fibrillation undergoing ablation?
Population
172 AF patients undergoing ablation
Comparison
Lower vs higher LASr, and correlation of LAS with LAP
Design

Implication
LA strain may estimate pressures noninvasively in AF during sinus rhythm; leaves open clinical adoption pending validation.
Structured PICO
Does left atrial strain assessed by echocardiography correlate with directly measured left atrial pressures in patients with atrial fibrillation undergoing ablation?
P
Population
172 patients with atrial fibrillation (AF) undergoing ablation (98 with sinus rhythm [SR] and 74 with AF)
I
Intervention
Left atrial strain (LAS) assessment by speckle tracking echocardiography
C
Comparator
Direct measurement of left atrial pressures (LAP) during ablation
O
Outcome
Correlation between left atrial strain (LAS) and directly measured left atrial pressures (LAP)surrogate
Left atrial strain assessed by speckle tracking echocardiography correlates with directly measured left atrial pressures and can estimate elevated LAP in patients undergoing AF ablation.
