Key result
Despite technical advances in catheter ablation for ventricular tachycardia, the arrhythmic recurrence rate remains approximately 50%.
Why the study?
Despite advances in electroanatomical mapping and ablation catheters, catheter ablation for ventricular tachycardia has an arrhythmic recurrence rate of approximately 50%, exposing patients to multiple invasive procedures and deleterious defibrillator shocks.
Highlights the potential of multimodality imaging fusion to guide stereotactic radioablation for refractory complex ventricular tachycardia.
Case report of novel VT ablation technique; leaves open need for prospective trials before clinical adoption.
Ventricular tachycardia (VT) is associated with a high risk of sudden cardiac death (SCD). The widespread implantation of defibrillators as an SCD prevention strategy has increased the number of survivors of VT or ventricular fibrillation. These arrhythmias represent a difficult-to-treat problem of great magnitude, with catheter ablation currently being the most accepted therapy.1 However, despite technical advances in electroanatomical mapping (EAM) and new ablation catheters, the arrhythmic recurrence rate is approximately 50%, exposing patients to multiple invasive procedures and potentially deleterious defibrillator shocks.
