Aim: The purpose of this study is to evaluate of the significance of the left atrial volume index (LAVI) measurement performed before ECV in predicting the recurrence of the AF. Methods and materials: Fifty-one patients with AF, selected for ECV were studied in the cardiology department of Tabriz University of medical sciences. The clinical and demographic data of all the patients were recorded. Echocardiography was performed before and also three months after ECV. Patients were divided into two groups: those who maintained SR and those with recurrent AF based on their clinical manifestations and ECG taken after three months. Results: SR was maintained in 76.5 percent of the patients following the three months after ECV. The age, sex and the BMI were not significantly different between SR and AF groups. Two groups showed no significant differences considering pre-ECV medical history including medications and systemic diseases. The initial LAVI was significantly different between two groups. The cut-off point of LAVI value in predicting the maintenance of SR was 55 ml/m2. The LAVI of SR group decreased significantly after three months. Conclusion: The present study demonstrates that LAVI is a powerful predictor of the recurrence of AF after ECV. The LAVI measurement could be a useful method in the selection of the patients with AF for ECV.
