  • Participation - no CE credit: 0.75


Persistent AF ablation is at another crossroads. Do you think PVI alone is sufficient, in which case why map? Instead perhaps you feel that a fixed lesion set is always indicated. Or do any of the patient specific AF mapping tools offer real insight into fundamental mechanisms to target?

This debate session is 45 minutes in length and is comprised of one chair and two invited speakers. Each speaker has up to 15 minutes to present their case followed by a five minute rebuttal.

Learning Objectives

  • To explain the rationale for alternative mapping strategies in persistent AF.
  • To identify which cases mapping may guide patient tailored therapy
  • To outline the anatomical approach to ablation of persistent AF with a fixed lesion set
  • To recognize spatial heterogeneity of driver sites as a need for disease specific mapping.

Target Audience

  • Physician
  • Electrophysiology Fellow
  • Cardiology Fellow
  • Physician Assistant
