Endocardial ablation of these sites resulted in non-inducibility of VT/VF post-ablation, and was associated with reduced recurrence of VT/VF episodes during short-term (mean 7 ± 6 months) follow-up. Isolated reports using this endocardial approach followed in the literature [ 22 ]. Unfortunately, a significant number of BrS patients undergoing EP study may not demonstrate focal PVCs at baseline, even with aggressive stimulation protocols, thereby limiting the usefulness of this approach [ 7, 23 ].
