Abstract:
Objective To analyze the distribution of key target sites(KTSs) during initial circumferential pulmonary vein isolation(CPVI) for atrial fibrillation(AF) and during re-ablation.Methods Forty eight cases(30 males,average age 54.3?10.2 years) with recurrent AF were enrolled.AF was paroxysmal in 24 cases and persistent in 24 cases.Re-ablation was performed 37.2?7.4 days after initial CPVI.KTS was defined as the target sites where pulmonary vein potentials(PVPs) delayed,conduction sequence changed,PVPs slowed down or PV isolated during ablation.Circumferential pulmonary vein(PV) lesions were divided eaqually into 8 segments.KTSs were analyzed during initial CPVI and re-ablation.Results One hundred and forty five KTSs were identified during initial CPVI.The mean KTSs per case were 3.02?1.08,compared with 1.58?1.09 during re-ablation,P
