Key result
Novel multipolar PFA catheter assesses PVI with ~97% accuracy at lower pacing outputs.
Why the study?
To validate the performance of a newly available multipolar PFA catheter compared to a standard pentaspline 3D-mapping catheter for endpoint assessment of PVI.
Does a novel multipolar PFA catheter accurately assess pulmonary vein isolation compared to a standard pentaspline 3D-mapping catheter in patients undergoing first PVI?
Observational (n=56)
Does a novel multipolar PFA catheter accurately assess pulmonary vein isolation compared to a standard pentaspline 3D-mapping catheter in patients undergoing first PVI?
A novel multipolar PFA catheter provides highly accurate real-time endpoint assessment for pulmonary vein isolation, with accuracy improving to 97% when pacing output is lowered to avoid far-field capture.

May aid real-time PVI assessment during procedures; leaves open whether accuracy gains improve outcomes in randomized trials.
Kueffer et al. (2022) conducted an observational in Pulmonary vein isolation (n=56). Multipolar pulsed-field ablation (PFA) catheter vs. Standard pentaspline 3D-mapping catheter was evaluated on Accuracy of PV assessment with the PFA catheter. A novel multipolar pulsed-field ablation catheter demonstrated 91% accuracy for endpoint assessment of pulmonary vein isolation, which increased to 97% when pacing output was lowered to 5 V/1 ms.
