Right Atrial Compartmentalization Using Radiofrequency Catheter Ablation for Management of Patients with Refractory Atrial Fibrillation

Abstract

Right atrial compartmentalization may alter the substrate for AF, thus improving the efficacy of previously ineffective antiarrhythmic drugs. Because it is relatively safe, it may be a reasonable adjunctive intervention to maintain sinus rhythm in patients with drug-refractory AF.
