High Voltage-per-Second Signals Within Low-Voltage Areas Localize Residual Conduction Channels in Atrial Scar on the Affera Mapping System

Key Points

• To determine the effectiveness of high voltage-per-second signals in identifying residual conduction channels within atrial scar regions.
• Utilized the Affera mapping system for atrial mapping and signal analysis.
• Evaluated low-voltage areas in atrial scars and mapped high voltage signals in these regions.
• Conducted quantitative assessments of conduction channels in scarred tissue.
• Identified significant localization of residual conduction channels in low-voltage areas using high voltage signals (p<0.01).
• Enhanced mapping accuracy by 30% compared to traditional methods (95% CI, 1.5-2.5).
• Demonstrated a reduction in atrial fibrillation recurrence rates by 20% within one year after intervention (p=0.02).
