Implication
VT ablation outcomes differ sharply by substrate; extends observational data but leaves open randomized survival trials.
Structured PICO
P
Population
493 consecutive patients referred for ventricular tachycardia (VT) ablation, mean age 57+/-16 years, 358 male. Subgroups included 131 with no structural heart disease (SHD), 213 with ischemic cardiomyopathies (ICMP), and 149 with nonischemic cardiomyopathies (NICMP).
I
Intervention
Ventricular tachycardia (VT) ablation
O
Outcome
Abolition of all monomorphic VTs and long-term mortality at mean follow-up of 3.3+/-2.4 yearshard clinical
Ventricular tachycardia ablation is highly effective and associated with excellent long-term survival in patients without structural heart disease, whereas mortality remains significant in those with ischemic or nonischemic cardiomyopathy despite ablation.
