Study limitations
Our study has several limitations. First, it was a descriptive retrospective single-center analysis and consisted of a relatively small population who were strictly selected and eligible for VT ablation. Second, the implementation of PES after VT ablation in patients who were not inducible before VT ablation depends on the institutional or operator’s discretion. Therefore, generalizability is unknown although this study’s finding provided important real-world information that has never been described so far. Further investigations to evaluate the generalizability in a multicenter-manner are needed.
