Abstract

We have read with great interest the article “Efficacy of Catheter Ablation for Premature Ventricular Contractions (PVC) in Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)” by Assis F.R. et. al. PVC ablation in ARVC was previously studied by Aras D. et al and they presented successful results.In this study, we believe that the study should not be considered as unsuccessful since 2 patients showed a decrease in PVC burden by more than 80% and in the other three patients between 45-70%. The demonstration of a decrease in PVC burden with catheter ablation in ARVD patients indicates that a second ablation may increase the success rate and decrease symptoms. The fact that ARVC has a complex substrate and the disease can progress is undoubtedly the most important factor in achieving the desired success with PVC ablation. Epicardial ablation with endocardial ablation has increased the chance of success in this patient group. In addition, given that BCSD ablation and basal heart rate are guaranteed by ICD implantation, we think that administration of the maximum dose of antiarrhythmic medication may create a significant improvement in these patients. And another factor, contact force sensing plays an important role in evaluating the effectiveness of the process. We suggest that with the current treatment modalities, a pharmacoablative combination therapy and re-ablation when necessary would be appropriate for such a complicated disease.
