Effect of biventricular pacing on ventricular tachycardia recurrence after catheter ablation
- Of 795 consecutive patients who underwent catheter ablation (CA) for ventricular tachycardia (VT)
- propensity score matching (1:1)
Authors' conclusion
Bi-V pacing with an LV lateral wall substrate was associated with increased VT/ventricular fibrillation recurrence after CA.
Study context
- Population
- Patients with structural heart disease who underwent catheter ablation (CA) for ventricular tachycardia (VT)consecutive patients who underwent CA for VT, 384 met the inclusion criteria, 146 patients per group after matching
- Participants
- 795 patients
- Comparison
- Biventricular (Bi-V) pacing group vs intrinsic rhythm group
- Bi-V pacing groupn = 146
- intrinsic rhythm groupn = 146
Main finding
As reported in the abstract
All-cause mortality · median follow-up 473 days
Further findings
Heart failure hospitalization · median follow-up 473 days
VT/ventricular fibrillation recurrence · median follow-up 473 days
VT recurrence in patients with lateral wall VT origins
- Heart failure hospitalization: log-rank P = .63
- VT/ventricular fibrillation recurrence: log-rank P < .01
- VT recurrence in patients with lateral wall VT origins: log-rank P < .01
VT recurrence with lateral wall VT origin in the absence of Bi-V pacing
- In the absence of Bi-V pacing, a lateral wall VT origin was not associated with greater VT recurrences
