Patient, male 67 years old, preoperatively diagnosed with unstable angina and atrial fibrillation, underwent coronary artery bypass + RF ablation of atrial fibrillation under general anesthesia without cardiac arrest and without extracorporeal circulation support on May 27, 2013, first bypassed the left internal mammary artery and anterior descending branch, ascending aorta – saphenous vein – posterior descending branch, then, applied bipolar RF pen, performed four left and right pulmonary veins orifice isolation, postoperative atrial fibrillation disappeared, restored Sinus rhythm was restored, and on the 5th day after surgery, the incision healed in one stage and was discharged from the hospital. On the 5th postoperative day, the incision healed in one stage and he was discharged. The incidence of coronary artery disease combined with atrial fibrillation is clinically around 5%, with the increase of elderly patients, and the increase of requirements for quality of life improvement, most patients require a single operation to treat two diseases, at present, Beijing Anzhen Hospital, this surgical group of simultaneous coronary artery bypass graft + atrial fibrillation radiofrequency ablation has become a routine procedure, greatly improving the quality of life of patients after surgery, at the same time, saving medical costs. The cost of radiofrequency ablation of atrial fibrillation catheter alone is 80,000 yuan, and the cost of bypass alone is 80,000 yuan, so the total cost of bypass and atrial fibrillation radiofrequency ablation in this case is 110,000 yuan.
