Early Referral for Ablation of Scar-Related Ventricular Tachycardia Is Associated With Improved Acute and Long-Term Outcomes
Why the study?
Does early referral for catheter ablation (within 30 days) reduce VT recurrence and cardiac mortality in patients with scar-related ventricular tachycardia?
Population

Implication
Early ablation was associated with lower VT recurrence but not survival; hypothesis-generating for optimal timing in scar-related VT.
Structured PICO
Does early referral for catheter ablation (within 30 days) reduce VT recurrence and cardiac mortality in patients with scar-related ventricular tachycardia?
P
Population
300 patients after catheter ablation of sustained scar-related ventricular tachycardia
I
Intervention
Catheter ablation performed within 30 days after the first documented VT (early referral)
C
Comparator
Catheter ablation performed between 1 month and 1 year, or >1 year after the first VT occurrence
O
Outcome
Noninducibility of any VT after CA (acute success), VT recurrence and cardiac mortality after 2 yearshard clinical
Early referral for catheter ablation of scar-related VT within 30 days of first documentation is associated with improved acute success and lower VT recurrence, but not improved survival.
