Why the study?
Does radiofrequency ablation reduce VPB recurrence in patients with frequent VPBs originating from the RVOT compared to antiarrhythmic medication?
Does radiofrequency ablation reduce VPB recurrence in patients with frequent VPBs originating from the RVOT compared to antiarrhythmic medication?
Catheter ablation is more effective than antiarrhythmic drugs for preventing recurrence of right ventricular outflow tract ventricular premature beats, with QS morphology in lead I predicting better ablation outcomes.
May support ablation over AADs for RVOT VPBs; leaves open need for RCTs before practice change.
Catheter ablation is more efficacious than AADs for preventing VPB recurrence in patients with frequent VPBs originating from the RVOT. QS morphology in lead I was associated with better outcome after ablation.
