Key result
Ablation of the origin and preferential pathway serves as a successful alternative target for eliminating premature ventricular contractions when standard exit site ablation is difficult.
Why the study?
Does ablation of the origin and preferential pathway eliminate premature ventricular contractions when exit site ablation is difficult?
Does ablation of the origin and preferential pathway eliminate premature ventricular contractions when exit site ablation is difficult?
Targeting the origin and preferential pathway may be an effective alternative strategy for PVC ablation when standard exit site ablation is challenging.
May offer alternative ablation target for refractory PVCs; hypothesis-generating and requires prospective validation.
However, the common strategy for eliminating premature ventricular contractions (PVCs) is to explore the exit site and ablate, which may be difficult in some cases. The origin and the preferential pathway, an insulated pathway connected to the exit, may also become targets for eliminating PVCs.
