About

The MAP-AF study will compare RHYTHMIA vs CARTO in redo ablation of paroxysmal AF with assessment of both acute procedural profiles and clinical outcomes.

Full description

Pulmonary venous conduction recovery is found in most patients undergoing redo ablation procedures for atrial fibrillation (AF). Identifying gaps in prior ablation lines is essential to achieve successful outcomes. High density mapping systems have been proposed to allow the identification of such gaps with speed and accuracy.

The MAP-AF study will compare RHYTHMIA vs CARTO in redo ablation of paroxysmal AF with assessment of both acute procedural profiles and clinical outcomes.

Inclusion criteria

  • Adult patients (18-90 years of age) undergoing redo ablation procedures for paroxysmal AF regardless of the systems or energy sources used during the pre-study ablation procedure(s).
  • Paroxysmal AF: defined as AF terminating within 7 days of onset either spontaneously or with electrical or medical cardioversion.

Exclusion criteria

  • Persistent AF
  • Prior cardiac surgery
  • Patients with only AFL or AT as the documented recurrent arrhythmia after the pre-study AF ablation(s).
