【摘要】 ８例三尖瓣下移畸形并右侧旁路患者行射频消融，平均室上速发作病史１１年。成功消融７例共８条旁束。结果表明：射频消融术前先行右室造影有利于消融靶点定位，射频消融术是治疗三尖瓣下移畸形并房室折返性心动过速安全、有效的方法。更多还原

【Abstract】 Patients with atrioventricular accessory reentrant tachyardias (AVRT) associated with congenital heart diseases of Ebstein’s anomaly underwent radiofrequency catheter ablation (RFAC) therapy. The average history of paroxysmal supraventricular tachycardia was 11 years. Eight atriventricular accessory pathways in seven patients were successful ablated. The results showed that right ventricular radiography before RFCA was useful for accessory pathways location, RFCA in patients with AVRT in congential heart disease was both safe and effective.更多还原
