Impact of catheter ablation for atrial fibrillation on cardiac ventricular electrical activity: assessment of premature ventricular complex burden

PVI significantly reduces PVC burden in most patients, independent of AF recurrence or ablation modality. Diabetes and impaired ventricular function identify patients at risk of persistent high PVC burden. PVI may particularly benefit AF patients with symptomatic PVCs, but larger prospective studies are needed to validate these findings and assess clinical outcomes.
