Objective To analyze the long-term efficacy and its influencing factors in the treatment of the permanent atrial fibrillation(AF) using monopolar radiofrequency ablation during concomitant cardiac valve replacement surgery with rheumatic heart disease. Methods Clinical data of the 116 patients with rheumatic heart disease and permanent AF who underwent modified maze procedure using monopolar radiofrequency ablation and concomitant cardiac valve replacement in the affiliated hospital of Qingdao university from October 2004 to December 2010 were collected and retrospectively analyzed, including 43 males and 73 females with their age of 50.5±7.5 years. Electrocardiogram (ECG) with 12-lead and echocardiography data, as well as the related complications, cardiac function and life quality were collected at the time of the immediately after the operation, discharge from hospital, 3 months, 6 months, 1 year postoperatively and every year after the operation. Patients were divided into eliminating group of AF (including sinus rhythm and nodal rhythm) and AF group according to the results of the ECG at the time of the ending follow-up. In the eliminating group of AF, there were 52 patients (16 males, 36 females) with their age of 48.4±7.3 years, and in the AF group, there were 50 patients (22 males, 28 females) with their age of 51.9±7.1 years. Analyzed the difference of the related factors between the two groups using statistical methods and tried to find the factors affecting the long-term clinical efficacy of the operation. Results Three patients died in hospital (one died of the hemolysis, acute renal insufficiency and hyperkalemia. One died of the multiple organ dysfunction syndrome caused by the acute renal insufficiency. And the other one died of the multiple organ dysfunction syndrome caused by the repetitive ventricular tachycardia and ventricular fibrillation on the day of the automatic discharge). Three patients died during the follow-up (one died after the reoperation because of the perivalvular leakage in other hospital, and the causes of death in the two others could not be catched). One patient occurred cerebral embolism, and the other one occurred cerebral hemorrhage in the af group during the follow-up. There was statistical significance between two group at the aspects of age, preoperative AF duration, preoperative left atrium diameter, time of the cardiopulmonary bypass and time of the cross-clamp ascending aorta. In multivariate analysis, age and preoperative left atrium diameter are risk factors affecting the long-term efficacy. Conclusion The treatment of the permanent atrial fibrillation using monopolar radiofrequency ablation concomitant cardiac valve replacement with rheumatic heart disease is effective and has good long-term efficacy. The factors of affecting the long-term clinical efficacy are the patient's age and the diameter of left atrium.
