Population

Patients undergoing pulmonary vein isolation (PVI) for atrial fibrillation

Intervention

Pulmonary vein isolation (PVI) with radiofrequency (RF) ablation

Outcome

Incidence, location, and cause of recovery of electrical connections between the pulmonary veins and the left atriumsurrogate

Electrical connection recovery after PVI typically occurs at the edges of original connections, suggesting that additional targeted RF lesions may help reduce AF recurrence.

Abstract

Electrical connection recovery occurred most commonly at the edges of original ECs and occasionally at the mid-portion of continuous broad original ECs after PVI probably due to tissue oedema neighbouring the segmental RF lesions. Further RF lesions at the edge of original ECs and linear ablation to the continuous broad ECs may help reduce AF recurrence.
