Why the study?
Does a PV map using a 20-pole circular mapping catheter improve the identification of conduction gaps and facilitate complete PV isolation in AF patients after failed initial CPVA?
Does a PV map using a 20-pole circular mapping catheter improve the identification of conduction gaps and facilitate complete PV isolation in AF patients after failed initial CPVA?
A PV map created with a 20-pole circular mapping catheter and 3D navigation system effectively identifies conduction gaps after initial CPVA, enabling successful PV isolation with minimal additional ablation.
