Does pulsed field ablation compared to cryoballoon ablation improve efficacy and cardiac function in patients undergoing pulmonary vein isolation for atrial fibrillation?
While pulsed field ablation and cryoballoon ablation have similar efficacy for preventing AF recurrence, pulsed field ablation may offer additional benefits for left atrial reverse remodeling and left ventricular systolic function.
In our study, we show that CBA and PFA for PVI are of similar efficacy when it comes to AF recurrence. However, our findings suggest that PFA rather than CBA might induce left atrial reverse remodeling thereby contributing to left ventricular systolic function.
Rattka et al. (Fri,) studied this question.
