Abstract:
Objective To evaluate the relationship between early recurrences and long-term success in patients with paroxysmal atrial fibrillation (PAF) after electrical isolation of myocardial sleeves, and the mechanism of the delayed effects for early recurrences of paroxysmal atrial fibrillation after pulmonary vein ablation. Methods Guided by circular mapping catheter, 131 paroxysmal atrial fibrillation patients underwent the electrical isolation of muscle sleeves around the circumference of the targeted veins at the ostia until the achievement of electrical disconnection between the atria and veins. Results One hundred and four patients were followed up 112?37 days after ablation, of whom 59 (56.7%) were in sinus rhythm and PAF free, whereas 7 experienced remarkable reduction of PAF episodes. However, after the mean 380?226 days of follow-up, 81 cases (78%) were in sinus rhythm and PAF free, whereas 4 experienced remarkable reduction of PAF episodes. Conclusion Early recurrence of PAF did not mean the failure of the ablation of AF. Some patients may experience delayed success after a long-term follow-up.
