Abstract:
Objective To evaluate the effect of novel modified bipolar radiofrequency(RF) ablation for preoperative atrial fibrillation(AF) combined with off-pump coronary artery bypass grafting(OPCABG) for patients with AF and coronary artery disease(CAD).Methods From January 2007 to January 2014, 49 patients with AF, and CAD underwent the novel modified bipolar RF ablation combined with OPCABG in our department, 29 males and 20 females(11 paroxysmal, 19 persistent and 19 long-standing persistent).The patients were followed up with 24 hours Holter monitoring and echocardiography for (37.89 ± 18.1) months after the procedure.Results There were no perioperative death, serve low cardiac output syndrome or permanent pacemaker implantation.Mean AF ablation time was(33.2 ± 5.2) min, and the mean OPCABG time was(90.3 ± 16.6) min.Mean ICU stay time was(4.7 ± 2.5) days, and mean postoperative time was(14.5 ± 6.1) days.The maintenance of sinus rhythm was 93.9% (46/49) at discharge, while the rate was 83.7 % (41/49) one year later.Follow-up echocardiography data at 6 months postoperatively showed that left atrial diameter was significantly reduced and left ventricular ejection fraction was significantly increased.Conclusion The novel modified bipolar RF ablation combined with OPCABG procedure was safe, feasible and effective.It may be useful in selecting the best ablation approaches for patients with AF and CAD.
