简介
Background
The impact of catheter ablation of ventricular tachycardia (VT) on all-cause mortality remains unknown.
Objective
The purpose of this study was to examine the association between VT recurrence after ablation and survival in patients with scar-related VT.
Methods
Analysis of 2061 patients with structural heart disease referred for catheter ablation of scar-related VT from 12 international centers was performed. Data on clinical and procedural variables, VT recurrence, and mortality were analyzed. Kaplan–Meier analysis was used to estimate freedom from recurrent VT, transplant, and death. Cox proportional hazards frailty models were used to analyze the effect of risk factors on VT recurrence and mortality.
Results
One-year freedom from VT recurrence was 70% (72% in ischemic and 68% in nonischemic cardiomyopathy). Fifty-seven patients (3%) underwent cardiac transplantation, and 216 (10%) died …
