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.
