目的总结本院射频消融治疗局灶性房性心动过速(简称房速)的消融点、方法及疗效。方法分析5年间40例行射频消融治疗的房速患者的临床资料,探究消融靶点的分布、消融术的成功率和特殊起源点的消融方法,随访复发情况。结果 1起源于右房的房速多于左房(60%vs 40%)。右房常见消融点依次为右房间隔、界嵴、三尖瓣环、冠状窦口、上腔静脉和右心耳。左房常见消融点依次为肺静脉、左房间隔和左心耳。2射频消融治疗的成功率为85%(34/40)。85%的患者在En Site 3000三维标测指引下消融。3起源于右房间隔His束旁的6例房速通过无冠窦消融成功治愈4例,另2例于His束周围低功率消融失败。结论三维标测系统指引下行射频消融治疗局灶性房速效果肯定。His束旁起源的房速可通过主动脉无冠窦内消融。
Objective To summarize the ablation points, methods and therapeutic effects of radiofrequency ablation in patients with focal atrial tachycardia (referred to as atrial tachycardia). Methods The clinical data of 40 patients undergoing radiofrequency catheter ablation in 5 years were analyzed to investigate the distribution of ablation target, the success rate of ablation, the ablation method of special origin and the follow-up of recurrence. Results 1 Atrial derived from the right atrium was more atrial (60% vs 40%) than the left atrium. Right atrial ablation point followed by right atrial septum, border cristae, tricuspid annulus, coronary sinus, superior vena cava and right atrial appendage. Common left atrium ablation points followed by pulmonary veins, left atrial septal and left atrial appendage. 2 The success rate of radiofrequency ablation was 85% (34/40). 85% of patients underwent En Site 3000 3D mapping guidelines. 3 cases originated from the right atrial septum adjacent to the bundle of His 6 cases were successfully treated by non-coronary sinus ablation in 4 cases, the other 2 cases in the His bundle around the low-power ablation failed. Conclusion Three-dimensional mapping system guides the RF radiofrequency ablation for the treatment of focal atrial tachycardia effect. The velocity of the antrum adjacent to the origin of the bundle can be ablated through the aorta without a coronary sinus.
