Key result
Lumipoint ultra-high-density mapping detects residual antral potentials in ~62% more patients than propagation map analysis.
Why the study?
Low-voltage activity beyond pulmonary veins may contribute to long-term failure of AF ablation.
Does ultra-high-density mapping using the Lumipoint tool improve the detection of residual antral potentials and gaps during atrial fibrillation ablation?
Population
58 consecutive AF ablation patients from the CHARISMA registry
Design
Registry-based observational study
Follow-up
Mean 453 ± 133 days

May aid residual antral potential detection during AF ablation; leaves open impact on long-term durability.

Does ultra-high-density mapping using the Lumipoint tool improve the detection of residual antral potentials and gaps during atrial fibrillation ablation?
Absolute Event Rate: 58.6% vs 36.2%
p-value: p=0.025
Ultra-high-density mapping using the Lumipoint tool effectively identifies local vulnerabilities and residual potentials in antral lesion sets during AF ablation, even when pulmonary vein conduction is absent.
Solimene et al. (2022) conducted an observational in Atrial fibrillation (n=58). Ultra-high-density mapping (UHDM) with Lumipoint™ vs. Propagation map analysis was evaluated on Detection of residual antral potentials (RAPs) (p=0.025). Ultra-high-density mapping using Lumipoint™ detected residual antral potentials in more patients than propagation map analysis (58.6% vs. 36.2%, p=0.025), achieving 100% acute procedural success.
