Ablation procedures for rhythm control in patients with atrial fibrillation: clinical and cost-effectiveness analyses.

Atrial fibrillation (AF), which is the most common form of cardiac arrhythmia, is associated with high morbidity and mortality.1,2 Patients with AF are at a higher risk of clot formation and subsequent adverse hemodynamic events (such as stroke) because of the loss of atrial contractility, irregular ventricular rate of activity, and the loss of atrial appendage contractility and emptying.3 AF increases the risk of stroke four- to five-fold in...
