3.3.1 | Primary effectiveness endpoint
After a mean follow-up of 10.7±2.6 months (Table 3), freedom from atrial
tachyarrhythmia recurrence was achieved in 21 (65.6%) patients. Eleven
cases (34.4%) experienced atrial tachyarrhythmia recurrence, with 8
cases (25%) being AF recurrence and 3 cases (9.4%) being AFL
recurrence. The mean ablation-to-recurrence time was 5.2±2.9 months.
Three patients underwent a redo procedure, of whom 2 had AF recurrence
and 1 had typical AFL recurrence, which was determined to be
peri-tricuspid flutter during the redo procedure. All three patients
presented the reconnection sites of LPV and RPV located at the anterior
and posterior carina. LAPW reconnection occurred in one case, while both
MI and CTI were reconnected in all three cases.
