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.
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.
