efficacy and safety of different catheter ablation
technologies and of distal versus ostial pulmonary
veins (PV) isolation using the circular mapping
technique. BACKGROUND: Electrical isolation of the PVs
in patients with atrial fibrillation (AF) remains a
technical challenge. METHODS: Two hundred eleven
patients (163 men; mean age 53 +/- 11 years) with
symptomatic AF were included in this study. In the
first 21 patients (group 1), distal isolation (> or = 5
mm from the ostium) was achieved targeting veins
triggering AF. In the remaining 190 patients (group 2),
ostial isolation of all PVs was performed using 4-mm
tip (47 patients), 8-mm tip (21 patients), or
cooled-tip (122 patients) ablation catheters. RESULTS:
Distal isolation was able to eliminate premature atrial
contractions (PACs) and AF in six of 21 patients (29\%)
and 10 of 34 PVs. After a mean follow-up time of 6 +/-
4 months, no patients treated with the 8-mm tip
catheter experienced recurrence of AF, whereas 21\% (10
of 47 patients) and 15\% (18 of 122 patients) of the
patients ablated with the 4-mm tip and the cooled-tip
ablation catheters experienced recurrence of AF after a
mean follow-up of 10 +/- 3 and 4 +/- 2 months,
respectively. Significant complications including
stroke, tamponade, and severe stenosis occurred in
3.5\% (8/211) of patients. CONCLUSIONS: Catheter
technologies designed to achieve better lesion size
appeared to have a positive impact on procedure time,
fluoroscopy time, number of lesions, and overall
efficacy. Although distal isolation can be achieved
with fewer lesions, ostial isolation is required in the
majority of patients to eliminate arrhythmogenic PACs
and AF.",
