Abstract Objective： To summarize the clinical experience of the hameochronous bipolar radiofrequency ablation for congenital heart disease associated with atrial fibrillation under the open heart surgery. Method： From April 2008 to March 2009， 4 cases of congenital heart disease patient associated with atrial fibrillation were received the open heart surgery and the hameochronous bipolar radiofrequency ablation operation by cardiopulmonary bypass. The clinical data of 4 cases was analyzed retrospectively. Result： All operation achieved success. Operation time， cardiopulmonary bypass time， aortic clamp time and bipolar radiofrequency ablation operation n time were（ 228.25±31.75），（ 93.25±22.50），（57.50±20.75） and（ 17.75±2.25） minutes respectively. 3 patients were in sinus rhythm after the hearts beated again and 1 patient with ventricular fibrillation returned to sinus rhythm by electric defibrillation. No high degree atrioventricular block and death were found. Postoperative hospital stay was mean（ 9.25±1.25） days. All patients were in sinus rhythm when they were discharged from hospital. 4 patients were followed up from 5 to 6 years， and all were keeping in sinus rhythm. The postoperative right atrial diameter was reduced， compared with the preoperative right atrial diameter， the difference was statistically significant（P<0.05）. Conclusion： The hameochronous bipolar radiofrequency ablation for congenital heart disease associated with atrial fibrillation under the open heart surgery is a safe procedure， and has a high maintenance ratio of sinus rhythm for long-term.
