[4][5][6][7]14,18,19 It is still not known that which advanced echocardiography methods are superior in detecting PAF including tissue Doppler imaging and speckle tracking echocardiography and the conventional methods. Therefore, we do not know which echocardiography method should be used for diagnosis of suspected PAF.…”

Background It has been shown that transmitral A‐wave (TMAW) is affected in paroxysmal atrial fibrillation (PAF), and decreased left atrial contractions cause a decrease in the TMAW velocity. The relationship between TMAW acceleration time (TMAW‐AccT) and PAF is unknown. In this study, the predictive value of TMAW‐AccT for PAF was investigated. Methods Seventy PAF patients (mean age: 57.8 ± 11.0 years) and 70 control patients (mean age: 58.1 ± 10.5 years) were included in the study. Transthoracic echocardiography was performed in sinus rhythm in all patients. For TMAW‐AccT, the time between the basal point of the A‐wave and the highest point reached was measured. Results Transmitral A‐wave ‐AccT was significantly longer in the PAF group than the control group (TMAW‐AccT; 88.5 ± 18.1 vs 77.2 ± 16.4 ms, P = .000, respectively). The left atrial diameter and the left atrial volume index were similar between the groups (P = .07, P = .18, respectively). According to a multivariate logistic regression analysis, the TMAW‐AccT (OR: 1.02, 95% confidence interval 1.02–1.07, P < .001) was a predictor of PAF. A receiver operating characteristic curve analysis showed a cutoff value of TMAW‐AccT of >82 ms (sensitivity: 65.7%, specificity: 64.3%, positive predictive value: 64.8%, negative predictive value: 65.2%). Conclusion Transmitral A‐wave‐AccT can be used as an early marker in detecting PAF without dilated left atrium.

Left atrial and left atrial appendage function in paroxysmal atrial fibrillation

Abstract: In PAF patients Aa velocity is useful to assess LA function and correlates positively with other TTE derived LA functional parameters and LAA function by TEE derived PLAAEFV.
