• radiofrequency ablation ^a  

Why?

• In patients with at least 2 episodes of symptomatic atrial flutter, radiofrequency ablation reduces hospital admission and development of atrial fibrillation compared with medical therapy. ^a

Paroxysmal atrial flutter: radiofrequency ablation reduces hospital admission and AF onset compared with medical therapy

Patient	Treatment	Comparison	Outcome	CER	RRR (95% CI)	NNT (95% CI)
2 or more symptomatic episodes of atrial flutter a	radiofrequency ablation	medical therapy	hospital admission at 21 months	63%	64% (28% to 82%)	2 (2 to 6)
			development of AF at 12 months	53%	46% (-4% to 71%)	4 (2 to 290)
