Methods
This is a single-center, observational retrospective study including
consecutive patients with SHD and documented sustained monomorphic VT
(SMVT) referred to our center for VT ablation. All patients undergoing
VT ablation in our center are prospectively included in a dedicated
database. Baseline clinical, imaging and analitics data as well as
procedural and follow-up details are included in this database. Patients
were included in the final data analysis only if a baseline programmed
ventricular stimulation (PVS) protocol aiming for VT induction was
performed after substrate mapping and before ablation. All patients gave
informed consent and the study was carried out following the
recommendations of the ettical committee of the Hospital Universitari i
Politècnic La Fe.
