Results
A total of 203 VT ablation procedures were performed in 163 patients with SHD in our institution from March 2011 to September 2019. In 3 patients PVS was not performed before ablation due to baseline hemodynamic inestability and were not included in the study. The remaining 160 patients were finally included in the analysis and were distributed according to the results of baseline PVS (figure 1): group 1 (not inducible patients) n=18, group 2 (1 VT morphology induced) n=53, and group 3 (>1 VT morphology induced), n=89. In 4 patients the procedure was performed under mechanical hemodynamic support (ECMO in 3 patients and Levithronix in 1 patient). Baseline characteristics of the patients are described in table 1. Table 2 shows the principal findings during the VT ablation procedure.
