The aim of this study was to assess the effect of this novel procedure and to determine whether it can eliminate AF for CAD patients. From January 2007 to June 2013, 45 patients (26 male patients) with AF (9 paroxysmal, 17 persistent, and 19 long-standing persistent) and CAD underwent the novel modified bipolar RF ablation combined with OPCABG in our department. After median sternotomy, the modified bipolar RF ablation and OPCABG were performed on beating heart without cardiopulmonary bypass. Pulmonary vein isolation and left atrium ablation were achieved using a bipolar RF champ. Mitral annular lesion and ganglionic plexus were ablated with a bipolar RF pen. The left atrial appendage was excluded using a surgical stapler. 24h holter monitoring and echocardiography were performed at discharge and 3, 6, 12months postoperatively as well as every year thereafter. The modified bipolar RF ablation and OPCABG were performed successfully in all patients. Mean AF ablation time was 33.6±4.2min, and mean OPCABG time was 87.6±13.3min. Mean postoperative hospital stay was 12.6±5.5days. The maintenance of sinus rhythm was 95.6% (43/45) at discharge. There was no early death and permanent pacemaker implantation in perioperation. At a mean follow-up of 29.8±10.2months, 38 of 45 (84.4%) patients were in sinus rhythm. Follow-up TTE at 6months postoperatively showed that left atrial diameter was significantly reduced and left ventricular ejection fraction was significantly increased. The novel modified bipolar RF ablation procedure was safe, feasible and effective. It may be useful in selecting the best ablation approaches for patients with AF and CAD.
