Figure 3
Kaplan–Meier curves of (A) overall atrial arrhythmia recurrence, (B) AF
recurrence, (C) persistent AF recurrence, (D) atrial tachycardia
recurrence, and (E) persistent AF recurrence adjusted with several
factors (AAD use, age, body mass index, AF duration, LAD, and AF
duration) after the index ablation. The clinical outcomes for each
recurrence pattern were compared between patients with and without
additional LA roof cryoballoon ablation. The 12-month Kaplan–Meier
event-free rate estimates were the following: 79.0% vs. 72.2% (overall
recurrence), 83.0% vs. 73.8% (AF recurrence), 91.3% vs. 81.4%
(persistent AF recurrence), and 93.9% vs. 96.4% (AT recurrence). AADs,
anti-arrhythmic drugs; AT, atrial tachycardia; AF, atrial fibrillation;
LA, left atrial; LAD, left atrial diameter
