Authors' conclusion

In conclusion, LVA ablation in addition to PVI did not significantly reduce 1-year AF or AT recurrence in patients with persistent AF with left atrial LVAs.

Study context

Population
Patients with persistent atrial fibrillation (AF) and left atrial low-voltage areas ≥5 cm² on voltage map after pulmonary vein isolation (PVI)SUPPRESS-AF
Participants
170 vs 171
Comparison
PVI + LVA ablation vs PVI alone
  • PVI + LVA-ABLn = 170
  • PVI-alonen = 171reference
Primary endpoint
Freedom from AF or AT recurrence without antiarrhythmic drug use
Follow-up
1 year

Primary result

As reported in the abstract

P for log(rank) test = 0.127

Safety

Procedure-related serious adverse events

Procedure-related serious adverse events — No difference between the two groups
P < 0.0001
