Abstract
The purpose of this study was to investigate the relationship between the efficacy of the 2 different ablation techniques of atrial fibrillation (AF) and left atrial (LA) size. A total of 81 patients with paroxysmal AF (n = 58) or persistent AF (n = 23) refractory to antiarrhythmic drugs underwent circumferential pulmonary vein isolation (PVI; n = 45) or PVI (n = 36) without respect to echocardiographic results for LA volume index (LAVI). Of the 81 patients, 41 had less dilated LA (group 1; LAVI < 27 cc/m(2)) and 40 had dilated LA (group 2; LAVI > or = 27 cc/m(2)). During the 9-month follow-up, 33 patients (73.3%) after circumferential PVI and 18 (50%) after PVI (P = .031) were free of arrhythmia. The risk of recurrence was associated with persistent AF, hypertension, LAVI > 27 ml/m(2), PVI, early recurrence of AF, and lower left ventricular (LV) ejection fraction (all P value <.05). In the univariate analysis of each group, PVI (hazard ratio [HR]: 2.92, 95% confidence interval [CI]: 0.12-7.08, P = .018) was associated with late recurrence only in group 2. Cox regression analysis also showed that PVI (HR: 5.6, 95% CI: 1.9-16.56, P = .002) was a significant independent predictor of recurrence only in group 2. Circumferential PVI...Continue Reading
