Abstract

Purpose: We hypothesized that inducibility of the VT responsible for ICD therapies at the end of RFCA, would also be associated with a differential risk, depending on left ventricular function. Methods: We retrospectively studied 66 patients with previous myocardial infarction and with ICD who also underwent RFCA for recurrent refractory VTs. Results: During the follow-up only 19 patients (29%) showed VTs. Among patients with ejection fraction (EF) ≤ 35%, 11 out of 25 still continued to have VT recurrences, independent of the inducibility of the VT. Among patients with EF >35% and
