Key result
The AVAAR registry demonstrated that lattice-tip pulsed field ablation for ventricular tachycardia achieved 82% acute success, but raised safety concerns due to a 19.2% mortality rate at 6 months and a 20% complication rate.
Why the study?
Does lattice-tip pulsed field ablation improve acute success and safety in patients with ventricular tachycardia?
Does lattice-tip pulsed field ablation improve acute success and safety in patients with ventricular tachycardia?
While pulsed field ablation offers theoretical advantages for ventricular tachycardia, current observational data highlight significant safety concerns, underscoring the need for standardized protocols and randomized trials.

Biase et al. (2025) conducted an editorial in Ventricular Tachycardia (n=126). Lattice-tip pulsed field ablation (PFA) with or without radiofrequency (RF) was evaluated on Safety and acute success (VT non-inducibility). The AVAAR registry demonstrated that lattice-tip pulsed field ablation for ventricular tachycardia achieved 82% acute success, but raised safety concerns due to a 19.2% mortality rate at 6 months and a 20% complication rate.
