Key result
Targeting non-PV triggers is required for persistent AF ablation despite durable PVI.
Why the study?
Enduring isolation of the pulmonary veins is increasingly common in patients undergoing repeat catheter ablation for atrial fibrillation, requiring tailored ablation strategies.
Describes a clinical approach to repeat catheter ablation in a patient with persistent atrial fibrillation and enduring pulmonary vein isolation, focusing on non-PV triggers.
Non-PV triggers warrant consideration in repeat AF ablation with enduring PV isolation; hypothesis-generating for strategy.
Enduring isolation of the pulmonary veins (PV) is becoming increasingly common in patients undergoing repeat catheter ablation for atrial fibrillation. We describe our approach to ablation strategy in a patient with enduring isolation of PV and briefly discuss the role of non-PV triggers.
