Abstract EN
Background.
There are little comparative data on catheter ablation of paroxysmal atrial fibrillation (AF) using the contact force radiofrequency (CF-RF) catheter versus the second-generation cryoballoon (CB2).
Methods and results.
This is a single center, retrospective, nonrandomized study of 98 patients with symptomatic, drug-refractory paroxysmal AF who underwent their first PVI ablation using either the CB2 (n=40) or CF-RF (n=58).
The mean age was 60 years with 63% men, a mean LA size of 42 mm.
The procedure duration (74±17 versus 120±49 minutes p<0.05) was shorter for CB2 group; the fluoroscopy time (14±17 versus 16±5 minutes, p=0.45) was similar.
Complete PVI was achieved in 96% of patients with RF-CF and 98% with CB2.
Phrenic nerve palsies (2 transient and 1 persistent) occurred exclusively in the CB2 group and 1 severe, nonlethal complication (pericardial tamponade) occurred in the CF-RF group.
At 24-month follow-up, the success rate, defined as freedom from AF/atrial tachycardia (AT) after a single procedure without antiarrhythmic drug, was comparable in CF-RF group and CB2 group (65.5% versus 67%, resp., log rank p=0.54).
Conclusion.
Both the CB2 and the RF-CF ablation appeared safe; the success rate at 2 years was comparable between both technologies.
