BACKGROUND: Postablation atrial tachycardia (AT) is a significant complication following radiofrequency (RF) pulmonary vein isolation (PVI). Cryoballoon (CB) ablation is an alternative technique for PVI that appears to have a low incidence of AT. No direct comparison between AT risk in RF and CB ablation has been made. OBJECTIVE: To compare the incidence and characteristics of ATs after PVI with RF and with CB ablation in patients with paroxysmal atrial fibrillation (AF). METHODS: All patients who underwent their first PVI between January 2006 and September 2012 using either RF or CB ablation were included. When a repeat ablation procedure for AT was performed, the arrhythmia was classified as typical cavotricuspid isthmus (CTI) flutter or left atrial tachycardia (LA-AT) based on invasive mapping procedure findings and ECG P-wave morphology. RESULTS: The study population consisted of 415 and 215 consecutive patients in the RF and CB groups, respectively. After a mean follow-up of 38 ± 21 months, 52 (8.3%) patients presented ATs (9.4% and 6% in the RF and CB groups, respectively; P = 0.15). Of those, 26 (4.1%) were classified as LA-AT with 20 (4.8%) in the RF group and 6 (2.8%) in the CB group (P = 0.23). In patients without a history of typical CTI flutter or CTI line (n = 458), the incidence for this type of arrhythmia during follow-up was 3.5%. CONCLUSION: In patients with paroxysmal AF undergoing either RF or CB PVI as the sole ablation strategy, the incidence of postprocedural AT was low and there was no significant difference between the 2 techniques.
