- Abstract
- The aim of this study was to assess the clinical and echocardiographic predictors for the recurrence of persistent atrial fibrillation (AF) after ablation during a long-term period. A total of 130 patients with persistent AF who had undergone radiofrequency catheter ablation (RFCA) were enrolled. We analyzed the relation between clinical parameters, echocardiographic parameters, and AF recurrences at 6 months, 1 year, and 2 years after ablation. During the 2-year follow-up, AF recurred in 61 patients (46.6%). In the 6 month follow-up, AF recurrence was associated only with total ablation time only. However, during the 1-year and 2-year follow-up periods, the presence of hypertension, impaired left atrial (LA) emptying fraction (eF) (<= 20%), decreased LA appendage (LAA) emptying velocity (<= 20 cm/sec), and LAAeF (<= 20%) were correlated with AF recurrence (odds ratio [OR] = 1.87, 2.45, 1.93, and 2.15 respectively, P = 0.016, 0.004, 0.029, and 0.004 respectively). Among these factors, impaired LAeF was the only independent predictor of AF recurrence in multivariate analysis (OR = 2.81, P = 0.012). In patients with persistent AF who had undergone RFCA, the best predictor of AF recurrence after ablation varied according to the follow-up period. Diminished LA function was the only predictor of recurrence in the 2-year follow-up. Pre-procedural assessment of LA function might be helpful in selecting those patients who would benefit from RFCA.
