Özet
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.
