Abstract:
Objective: To observe curative effect of radiofrequency catheter ablation (RFCA) and changes of cardiac function and left atrial diameter after operation in patients with atrial fibrillation (AF). Methods: A total of 28 AF patients with obvious clinical symptoms and without effective for drug therapy received RFCA in our hospital, their data were retrospectively analyzed.
They received RFCA under guidance of three dimensional electro-anatomic mapping (EAM) system. Changes of cardiac function and left atrial diameter were evaluated by echocardiography and curative effect was evaluated by ambulary blood pressure monitoring before, three and six months after operation. Results: Pulmonary vein isolation rate was 100% in all patients. No severe complication occurred during or after operation. After six-month follow-up, 27 cases(96.4%)did not recur AF among the 28 patients; Compared with before operation, there were significant decrease in left atrial diameter [(37.3±4.8) mm vs. (33.6±4.5) mm] and significant increase in left ventricular ejection fraction [(59.8±8.7) % vs. (64.2±6.8) %] by echocardiography, P<0.05 both. Conclusion: Radiofrequency catheter ablation is safe and effective in treatment of atrial fibrillation, and there are significant improvements in cardiac function and left atrial diameter.
