4.1 | Clinical efficacy
Our study showed a high rate of acute success in achieving PVI, LAPW isolation, CTI block, and MI block, along with a high rate of atrial tachyarrhythmia-free survival (65.6%) at 1 year post-ablation. Energy delivery for PVI and LAPW isolation was completed within several minutes, resulting in a shorter procedure time compared to studies using RFCA. The shorter procedure duration and reduced LA dwell time may contribute to decreased thrombus formation during the procedure. Besides, operators in our study were not experienced with PFA technology before, but application time and total procedure time still were reasonable.
