器质性心脏病合并室上性心动过速的射频消融治疗

目的 探讨器质性心脏病合并阵发性室上性心动过速射频消融的疗效和安全性.方法 对11例器质性心脏病合并房室折返性或房室结折返性心动过速患者进行了射频消融治疗,并与80例无器质性心脏病患者进行对照.结果 射频消融治疗的首次成功率为90.9%,无严重并发症.与对照组比较,手术时间和X线爆光时间长.结论 器质性心脏病合并阵发性室上性心动过速射频消融治疗仍安全有效,术前明确其解剖学改变和心功能状态,对于选择射频消融途径、增加成功率、减少操作时间及减低并发症具有重要意义.

Radiofrequency catheter ablation of supraventricular tachycardia in patients with structrual heart diseases

Objective To evaluate the efficacy of radiofrequency catheter ablation (RFCA) of paroxysmal supraventicular tachy-cardia(PSVT) in patients with structural heart diseases. Methods RFCA were performed in 11 patients with organic heart disease and atrioventricular or atrioventricular nodal reentrant tachycardia. 80 Patients without structural heart diseases served as control subjects. Results The first RFCA success rate was 90. 9% (10/11) without significant complications. Procedure and rada-tion exposure time were longer than that in control group. Conclusion PSVT in patients with structural heart diseases can be successfully treated by RFCA with a careful,anatomically precise approach. It is important to manifest the cardiovascular anatomy differentiation and cardiac function prior to ablatio for increasing the successful rate and decreasing complications.
