ObjectiveTo evaluate the efficacy and safety of cardiac surgery concomitant with bipolar radiofrequency ablation(BRFA) for the patients with heart disease and atrial fibrillation(AF). MethodsFrom April 2008 to September 2014, clinical data of 167 patients(43 males, 124 females) of organic-heart-disease patients combined with atrial fibrillation were analyzed retrospectively in our hospital. Within 167 patients, 102 patients underwent bipolar radiofrequency ablation without aortic cross-clamping were as a trial group and the other 65 patients underwent cardiac surgery and bipolar radiofrequency ablation with aortic cross-clamping were as a control group. And there were no significant difference in the age and gender between the two groups. ResultsThe time of radiofrequency ablation was 23.1±5.0 minutes in all the patients and there was no significant difference between the two groups(P=0.279). The extracorporeal circulation time was 156.6±56.4 minutes and the aortic cross-clamping time was 82.1±42.6 minutes. There was a significant difference between two groups in extracorporeal circulation time and aortic cross-clamping time. One patient underwent bipolar radiofrequency ablation with aortic cross-clamping died of severe pulmonary infection and multiple organ dysfunction syndrome(MODS) in one month after the surgery. The duration of follow-up was 1-77(35.3±3.5) months. The sinus rhyme conversion rate was estimated by electrocardiogram(ECG) in 1 month, 3 months, 6 months, 12 months, 36 months, 60 months after operation. The sinus rhyme conversion rates were 85.3%(133/156), 83.4%(126/151), 82.7%(115/139), 77.0%(94/122), 75.9%(41/54), and 72.0%(18/25). There was no significant difference during the follow-up in all of the sinus rhyme conversion rate. During the fellow-up, 2 patients died. One died after 1 month and another died after 6 months after their hospital-discharges. ConclusionThe efficacy and safety of cardiac surgery concomitant with bipolar radiofrequency ablation is satisfied. It can reduce the time of myocardial ischemia in bipolar radiofrequency ablation without aortic cross-clamping. It is beneficial to critical patients.
