Why the study?
What clinical and procedural variables predict ICD-therapy free survival in patients undergoing prophylactic catheter ablation of ventricular tachycardia?
What clinical and procedural variables predict ICD-therapy free survival in patients undergoing prophylactic catheter ablation of ventricular tachycardia?
The number of ventricular tachycardias induced during prophylactic ablation predicts 2-year ICD-therapy free survival, likely reflecting a more complex arrhythmia substrate.
No takes yet. Share an insight, caveat, or question.
Inducible VT burden may aid post-ablation risk stratification; leaves open whether targeting more VTs improves ICD-therapy-free survival.
Tung et al. (2010) studied this question.
