摘    要:Objective To evaluate the feasibility of mdiofrequency catheter ablation of atrial fibrilla-tion (AF) guided by complex fractionated atrial electrograms (CFAEs). Methods Twenty-two patients with drug refractory and symptomatic AF(16 paroxysmal, 6 persisten) were enrolled. Using Carto, the left atrial or biatrial replica was created during spontaneous or induced AF, and areas associated with CFAEs were identi-fied. Radiofrequency ablation at the site with CFAEs was performed and the end points were to eliminate CFAEs or convert to sinus rhythm. Results Thirteen patients(59%)were converted to sinus rhythm, (7 cases conver-ted directly to sinus rhythm, and 6 via the intermediate atrial tachycardia(AT) or atrial flutter (AFL). The re-maining nine patients required cardioversion with D. C. shock or drug. Repeat ablation was performed in 6 pa-tients (5 AT/AFL, 1 paroxysmal AF). During(10.9 ±4.8) months follow-up, 16 patients (73%) were free of arrhythmia and symptoms. CFAEs were most commonly found along the left interatrial septum, pulmonary veins, left atrial roof. CFAEs ablation prolonged AFCL[(157 ± 18) ms vs (211 ± 32) ms, P < 0.05]. Only one patient had pericardial tamponade that required pericardiocentesis. Conclusion Radiofrequeney catheter abla-tion of atrial fibrillation (AF) guided by CFAEs is safe and effective.
