Figure 5

At 2‐year follow‐up, in the LAA/CS isolation population, 134/147 (91.1%) patients from group 1 and 391/414 (94.4%) from group 2 remained arrhythmia‐free (log‐rank test, P‐value 0.19). Success rate in patients receiving lines and flutter ablation was 4/54 (7.4%) in group 1 and 3/42 (7.1%) in group 2 (0.86). Subgroup 1A and 2A received LAA/CS isolation. Subgroup 1B and 2B received lines and flutter ablation. CS indicates coronary sinus; and LAA, left atrial appendage.
