Abstract:
Objective To investigate the feasibility and efficacy of single ablation catheter for complete circumferential pulmonary vein antrum(PVA) isolation.Methods After performing initial circumferential lesions in 55 consecutive patients with paroxysmal atrial fibrillation,residual gaps were mapped and closed using single ablation catheter.Results The PVA isolation rates were 61.8%(34/55) in the right side,27.3%(15/55) in the left side,and 18.2%(10/55) in both sides,respectively.Twenty five gaps along the right PVA lesions and 49 gaps along the left PVA lesions were identified.All of these residual gaps were closed with single catheter approach.Mean procedure time and fluoroscopy time were 154?29(99-204) minutes and 32?7(19-49) minutes,respectively.Duration of radiofrequency energy delivery was 53?10(31-72) minutes.Conclusion Single ablation catheter technique is feasible and effective in localizing the residual gaps for complete isolation of the PVAs for ablation of paroxysmal atrial fibrillation.
