2.1. Study Population
From January 2009 to April 2020, 84 consecutive patients with SHD underwent RF ablation (116 procedures) for drug-resistant VT in our hospital. Patients who underwent multiple procedures were evaluated during the last procedure.
VT non-inducibility was achieved in 20 patients but it was not achieved in 64. To evaluate the validity of “VT non-inducibility” as an endpoint of RF ablation, 64 patients in whom VT non-inducibility was not achieved were studied. The study was approved by the ethics committee of Kobe University Hospital, and all patients gave their written informed consent.
