ClinConnect Summary

Background:

The efficiency of catheter ablation in drug-refractory atrial fibrillation (AF) is compromised by high incidence of post-ablation AF recurrences requiring multiple ablation procedures (1). Post-PVAI (pulmonary vein antrum isolation) AF recurrence is mostly due to reconnection of the previously isolated PVs (2). Earlier studies have revealed that elimination of dormant PV conduction revealed by adenosine-provocation ensures better outcome as reconnection mostly happens due to presence of incompletely ablated tissue and identification and complete ablation decrease chance of recu...
