Does any specific redo ablation strategy improve arrhythmia-free survival in patients with recurrent AF despite durable PVI?
In patients with recurrent AF despite durable PVI, the choice of redo ablation strategy does not significantly alter arrhythmia-free survival, whereas baseline left atrial size is a key predictor of success.
In patients with recurrent AF despite durable PVI, no ablation strategy used alone or in combination during the redo procedure appears to be superior in improving arrhythmia-free survival. Left atrial size is a significant predictor of ablation outcome in this population.
