Overview

Multicenter trial demonstrates acute MI block rates in atrial fibrillation patients, suggesting effective ablation strategies.

Key Points

  • To assess the feasibility, acute success, safety, and 1-year outcomes of posterior mitral line ablation using a dual-energy lattice-tip catheter.
  • Multicenter cohort study of patients undergoing atrial fibrillation ablation with posterior mitral line using dual-energy catheter.
  • Assessment of acute MI conduction block and arrhythmia-free survival at follow-up.
  • Analysis of complications and redo procedures.
  • Achieved acute MI block in 92.2% of patients.
  • 74.5% free from atrial arrhythmia after median follow-up of 356 days.
  • Seven patients had reconduction attributed to epicardial gaps.
