2. Figure 1
Patient classification based on the presence of a previously diagnosed structural heart disease (SHD) and changes in left ventricular ejection fraction (LVEF) during follow-up. Before premature ventricular complex (PVC) ablation, it is possible to classify patients only as those with or without previously diagnosed structural heart disease. After the completion of follow-up, patient can be classified into 4 groups: patients with a previously diagnosed SHD (PVC-worsened cardiomyopathy); patients with no previously diagnosed SHD and normalized LVEF (>50%) after PVC abolition (PVC-induced cardiomyopathy [CM]); patients with no previously diagnosed SHD and improved but not normalized LVEF after PVC abolition (nonischemic heart disease [NIHD] worsened by PVC); and patients without previously diagnosed SHD and without complete PVC abolition.

5. Figure 4
Number of patients with primary prevention (PP) implantable cardioverter-defibrillator (ICD) implant indication during follow-up, according to baseline premature ventricular complex (PVC) burden and the persistence of PVC abolition after ablation. Note that at the end of follow-up, ICD implantation was still indicated in only one of the patients with high PVC burden and successful sustained ablation, but was indicated in all patients with PVC burden <13%, regardless of ablation success.

Association between the absolute reduction of the baseline premature ventricular complex (PVC) burden (baseline PVC burden [%] – average 6-month and 12-month PVC burden [%]) and the change in left ventricular ejection fraction (LVEF) during follow-up.
