Atrial Fibrillation Ablation in Heart Failure with Reduced Ejection Fraction.

Multiple randomized clinical trials have demonstrated catheter ablation in heart failure with reduced ejection fraction reduces mortality and hospitalization as well as improves ventricular function, quality of life, and functional status. Catheter ablation has been shown to be superior to alternative rate and rhythm control strategies in these outcomes. Guidelines strongly support the use of catheter ablation to maintain sinus rhythm in patients with atrial fibrillation and heart failure.
