Arrhythmias & electrophysiologyCohort study
Safety and efficacy of a lattice-tip catheter for ventricular arrhythmia ablation: the AFFERA Ventricular Arrhythmia Ablation Registry (AVAAR)
- Multicentre registry study
- 18 European centres
Authors' conclusion
In this complex population with refractory VA, ablation using the lattice-tip catheter appears feasible and relatively safe.
