Catheter ablation for ventricular tachycardia is increasingly safe and effective, with studies showing up to 70% success rates and reduced ICD shocks, supporting its use earlier in treatment.
Advocates for earlier consideration of ablation in the treatment of ventricular tachycardia due to improved safety and efficacy from recent technological advances.
Ventricular tachycardia (VT) is a leading cause of morbidity and mortality for many patients, with a significant emotional and economic burden caused by implantable cardioverter-defibrillator (ICD) shocks and the requirement of medication with significant side effects. Additionally, 10% of VT occurs in patients with no structural heart disease. Until quite recently, ablation for VT has been reserved as the procedure of last hope for those who have ongoing recurrences despite maximal medical therapy and who are traumatized by multiple ICD shocks 1. However, recent advances in imaging technology and three-dimensional intracardiac mapping systems have significantly improved the safety and efficacy of VT ablation procedures. Thus, ablation for VT should no longer be reserved as a last-resort bailout procedure and should move into the realm of routine electrophysiology treatment.
Heather L. Bloom (Tue,) conducted a review in Ventricular tachycardia. Catheter ablation vs. Standard medical therapy was evaluated.
