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.
