摘　　要：目的 :分析风湿性心脏病 (RHD)慢性心房颤动 (AF)患者左心房大小和 AF病史长短与射频迷宫手术治疗AF疗效的关系。方法 :所有患者术前均做超声心动图检查左心房内径 ,询问 AF病史 ,按射频消融迷宫手术疗效分组比较。结果 :手术后恢复窦性心律 (恢复组 )患者和未恢复窦性心律 (未恢复组 )患者 AF病史长短和左心房大小有显著差异 (3.8± 3.2年 vs11.1± 8.7年 ,66± 10 mm vs82± 13m m,均 P<0 .0 1) ;AF病史≥ 3年的患者 AF转复率明显低于 AF病史 <3年的患者 (72 % vs96% ,P<0 .0 1) ;左心房长径≥ 70 mm患者 AF转复率明显低于左心房长径 <70 mm的患者 (62 % vs95 % ,P<0 .0 1)。结论 :AF病史长短和左心房大小明显影响射频迷宫手术的治疗效果 ,AF病史越长。AIM:To study the influence of left atrium size and AF duration on the result of radiofrequency ablation maze procedure(RAMP) in treating chronic atrial fibrillation(AF) for patients with rheumatic heart disease(RHD). METHODS: Echocardiography examination was made for all patients before operation and long dimension of left atrium and AF duration were recorded. The patients were divided and analyzed according to the result of radiofrequency ablation maze procedure. RESULTS: The difference of the AF duration and the left atrium long dimension between patients who restored and didn't restore was significant(3.8±3. 2 year vs 11.1±8.7 year,66±10 mm vs 82±13 mm, P <0.01 respectively). The percentage of patients who restored to sinus rhythm with AF duration <3 year was significantly higher than those with AF duration ≥3 year(72% vs 96%, P <0.01). The percentage of patients who restored to sinus rhythm with long dimension of left atrium <70 mm was significantly higher than those with left atrium dimension ≥70 mm (62% vs 95%, P <0.01). CONCLUTION:The longer the AF duration and the larger the left atrium are, the worse the effect of the RAMP is.
