Good responders to catheter ablation for long-standing persistent atrial fibrillation: Clinical and genetic characteristics

Despite a relatively high recurrence rate after RFCA for L-PeAF, patients with a shorter AF duration and smaller LA size showed a more favorable outcome. The rs2106216 polymorphism (ZFHX3) was independently associated with being good responders to RFCA for L-PeAF, especially with AF duration 12-65 months.
