Background The aim of this study was to investigate left atrial (LA) function and synchrony in paroxysmal atrial fibrillation (PAF) patients using two‐dimensional speckle tracking echocardiography (STE). Methods Forty‐five PAF patients and 30 healthy controls were enrolled. LA peak ventricular systolic longitudinal strain (LAS‐S) and strain rate (LASR‐S) and left atrial longitudinal strain (LAS‐A) and strain rate (LASR‐A) during late diastole were determined using STE, and the standard deviation of the time to peak (TPSD) of the regional strains was calculated to quantify LA dyssynchrony. TPSD during ventricular systole and late diastole were named SDs and SDa, respectively. Results Left atrial peak longitudinal strain during ventricular systole (LAS‐S) (29.34±8.57 vs 36.73±6.13), LASR‐S (1.27±0.311 vs 1.57±0.25), LAS‐A (13.11±4.91 vs 17.86±3.57), and LASR‐A (−1.51±0.58 vs −1.90±0.30) were reduced in the PAF group compared with the controls (P<.05 for all). SDs (8.11±3.00% vs 4.67±1.48%) and SDa (5.57±2.26% vs 3.11±1.13%) were greater in PAF patients than in the controls (P<.05 for both). Furthermore, PAF patients with normal LA sizes exhibited lower LAS‐S (P<.05), LASR‐S (P<.05), LAS‐A (P<.05), and LASR‐A (P<.05) values and increased SDs (P<.05) and SDa (P<.05) values compared with the controls. Multivariate regression confirmed that SDs and SDa were powerful parameters for differentiating PAF patients from controls (SDs: sensitivity, 83%; specificity, 72%; SDa: sensitivity, 81%; specificity, 76%). Conclusions Left atrial (LA) dysfunction and dyssynchrony in PAF patients can be detected with STE even in the absence of LA enlargement. STE‐derived SDs and SDa were powerful parameters for identifying PAF patients.

“…Finally, some results suggest that three-dimensional speckle-tracking echocardiography (3D-STE) is potentially more accurate than 2D-STE for assessment of LA dysfunction in patients with AF [37,38]. Mochizuki et al [39] assessed patients with paroxysmal AF and found that global LA strain determined by 3D-STE less than 28.9% was a predictor of AF recurrence after the first-time CA Moreover, 3D-STE global LA strain was a better predictor of AF relapse after CA than LA strain obtained by 2D-STE.…”

“…Much attention was paid to echocardiographic parameters providing an assessment of left atrial (LA) size and function. It was shown that an increased LA volume ( 6 , 7 ) and LA mechanical dyssynchrony ( 3 , 8 , 9 ) were independent predictors of AF recurrence after catheter ablation. However, different echocardiographic techniques were used in these studies, and they also differed in terms of study design and definitions of recurrence.…”
