Reducing the Risk of AF Recurrence

High Density Mapping and Ablation of Concealed Low Voltage Activity Within Pulmonary Vein Antra Results in Improved Freedom from Atrial Fibrillation Compared to Pulmonary Vein Isolation Alone -Segerson et. al.

Key Takeaways:

  • 90.7% of patients were free from AF when treated with the RHYTHMIA HDx™ Mapping System, compared to 73.9% when treated with traditional circular mapping catheter guided PVI.1
  • The RHYTHMIA-guided methodology included post-PVI voltage and activation validation mapping (vMapTM) to identify concealed low voltage signals in antral lesion sets.1
  • 20.7% of patients (31/150) had demonstrated residual PV antral activity that was eliminated with further ablation and confirmed by repeat vMaps. Targeting these areas resulted in improved freedom from AF.1
  • There was no increase in procedure times or complication rates by adding vMap to the PVI workflow in the RHYTHMIA-guided group.1

RHYTHMIA HDx combined with INTELLAMAP ORIONTM is the only system capable of collecting the quantity and quality of data required to uncover clinically relevant signals as low as 0.01mV, identifying local vulnerabilities that can become the source of AF recurrence.1
