Cryoballoon (CB) ablation is an alternative technique for PVI that appears to have a low incidence of AT.

When a repeat ablation procedure for AT was performed, the arrhythmia was classified as typical cavotricuspid isthmus (CTI) flutter or left atrial tachycardia (LA\u2010AT) based on invasive mapping procedure findings and ECG P\u2010wave morphology.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The study population consisted of 415 and 215 consecutive patients in the RF and CB groups, respectively. After a mean follow\u2010up of 38 \u00b1 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\u2010AT 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\u2010up was
