Overview

Observational study shows high freedom from arrhythmia in patients with coronary heart disease, suggesting the ablation index is a reliable marker.

Key Points

  • After 12 months, 84.8% of patients remained free from arrhythmia following catheter treatment.
  • Patients with no recurrence of VT had a significantly higher average ablation index of 612 compared to 438 in those with recurrence.
  • Ablation index values of 473 or higher may predict a lower risk of ventricular tachycardia recurrence.
  • This study supports the use of ablation index as a monitoring parameter during catheter procedures for VT.
