Catheter Ablation Versus Medical Therapy in Atrial Fibrillation With Heart Failure With Reduced or Mildly Reduced Ejection Fraction: A GRADE‐Assessed Systematic Review and Meta‐Analysis
ABSTRACT Background Catheter ablation is an established rhythm‐control strategy for atrial fibrillation (AF), but its effectiveness in patients with heart failure with reduced or mildly reduced ejection fraction (HFrEF/HFmrEF) remains incompletely defined. We performed a GRADE‐assessed systematic review and meta‐analys...
