Combined left atrial appendage occlusion and catheter ablation for atrial fibrillation versus isolated left atrial appendage occlusion: A systematic review and meta-analysis.

Background: Data on the effects of combined left atrial appendage occlusion (LAAO) and catheter ablation (CA) for atrial fibrillation (AF) remain limited. We aimed to perform a systematic review and meta-analysis comparing LAAO and CA versus isolated LAAO.

Methods: We systematically searched PubMed, Embase, and Cochrane Library for studies comparing combined LAAO and CA versus isolated LAAO in patients with atrial fibrillation.

Safety and efficacy of catheter ablation for atrial fibrillation in cancer survivors: a systematic review and meta-analysis.

Background: Cancer survivors are at increased risk for atrial fibrillation (AF). However, data on the efficacy and safety of catheter ablation (CA) in this population remain limited. Therefore, we aimed to perform a systematic review and meta-analysis comparing outcomes after CA for AF in patients with versus without prior or active cancer.
