Key result
Step-wise incremental radiofrequency catheter ablation successfully abolished frequent premature ventricular contractions originating from the His-bundle region without causing atrioventricular block.
Why the study?
Does step-wise incremental radiofrequency catheter ablation safely eliminate idiopathic frequent PVCs originating from the His-bundle region?

Does step-wise incremental radiofrequency catheter ablation safely eliminate idiopathic frequent PVCs originating from the His-bundle region?
Step-wise incremental radiofrequency catheter ablation can successfully and safely eliminate PVCs originating from the His-bundle region without causing atrioventricular block.
May support incremental ablation of His-bundle PVCs without AV block; hypothesis-generating and requires validation in prospective series.
We describe a 35-year-old man with idiopathic frequent premature ventricular contractions (PVCs) originating from the His-bundle region, where a low frequency ventricular potential was recorded in the bipolar recording and QR pattern in the unipolar recording. Electro-anatomical mapping revealed a confined low voltage zone (<1.2 mV) in the His-bundle region, and the activation spread out radially to the entire right ventricle. The PVCs were successfully abolished without any atrioventricular block by a step-wise incremental radiofrequency energy application to the His-bundle region. The patient has remained free from PVCs or any symptoms without medication during a 23 month follow-up period.

Ashikaga et al. (2007) conducted a case report in Idiopathic frequent premature ventricular contractions (PVCs) originating from the His-bundle region (n=1). Catheter ablation (step-wise incremental radiofrequency energy application) was evaluated on Abolition of PVCs without atrioventricular block. Step-wise incremental radiofrequency catheter ablation successfully abolished frequent premature ventricular contractions originating from the His-bundle region without causing atrioventricular block.
