目的探讨应用单纯房室旁道消融术治疗预激综合征伴心房颤动(房颤)的临床疗效。方法 34例预激综合征伴房颤患者,均给予单纯房室旁道消融术治疗,评估患者治疗的效果,观察患者并发症发生情况和房颤复发情况,比较手术前和术后3个月左心房内径的变化。结果 34例预激综合征伴房颤患者全部手术成功,手术即时成功率为100.00%,其中1例患者出现二度房室传导阻滞,并发症发生率为2.94%,为希氏束旁道,术后1周恢复传导功能。随访3个月,术后其中有1例出现房颤复发,复发率为2.94%。术后3个月患者的左心房内径为(29.42±2.26)mm,明显小于术前的(34.25±2.41)mm,差异具有统计学意义(P<0.05)。结论单纯房室旁道消融术治疗预激综合征伴房颤可有效消除房颤,且术后房颤复发率低、并发症少,安全有效,值得应用于临床。
Objective To investigate the clinical effect of simple atrioventricular bypass ablation for the treatment of WPW syndrome with atrial fibrillation (AF). Methods 34 patients with WPW syndrome and atrial fibrillation were treated with simple atrioventricular ablation. The therapeutic effect was evaluated. The incidence of complications and the recurrence of atrial fibrillation were observed. Three months before and after surgery Left atrial diameter changes. Results All 34 patients with WPW syndrome and atrial fibrillation were operated successfully. The immediate success rate was 100.00%. One case had second degree AV block and the complication rate was 2.94% , 1 week after surgery to restore conduction. Follow-up 3 months, 1 case of postoperative recurrence of atrial fibrillation, the recurrence rate was 2.94%. The diameter of the left atrium was (29.42 ± 2.26) mm at 3 months postoperatively, which was significantly lower than that of the preoperative (34.25 ± 2.41) mm, the difference was statistically significant (P <0.05). Conclusions Simple atrioventricular bypass ablation for the treatment of WPW syndrome with atrial fibrillation can effectively eliminate atrial fibrillation, and postoperative recurrence rate of atrial fibrillation is low, less complications, safe and effective, and should be used in clinical practice.
