Long-term outcomes of catheter ablation in patients with longstanding persistent atrial fibrillation lasting less than 2 years

摘要

Introduction: Outcome data after catheter ablation (CA) for longstanding persistent atrial fibrillation (LSPAF) lasting less than 2 years are limited and highly variable with different ablation approaches. We aimed to assess the long-term outcomes in patients with LSPAF lasting less than 2 years undergoing extended pulmonary vein antrum isolation (PVAI) versus those with additional non-pulmonary vein (PV) trigger ablation. Methods and
