目的 总结房室旁道射频消融治疗的经验。方法心内电生理检查与射频消融同步进行。结果 40例患者中,左侧旁道24例,消融成功率100%;右侧旁道16例,消融成功率69%,未成功的5例患者中,His旁道3例,右后侧壁旁道1例,右中间隔旁道1例。总成功率88%。其中1例术中出现短暂一度房室传导阻滞,未见其他并发症。结论准确标测靶点图,是消融成功的前提。右侧旁道由于解剖部位的特殊性,其RFCA的成功率低于左侧。
Objective To summarize the experience of radiofrequency ablation of atrioventricular bypass. Methods Cardiac electrophysiological examination was performed simultaneously with radiofrequency ablation. Results Among the 40 patients, 24 cases of the left accessory pathway and 100% success rate of ablation, 16 cases of the right accessory pathway and 69% of ablation success rate. Among 5 unsuccessful patients, 3 cases were His accessory pathway, 1 case of bypass, right side of the bypass in 1 case. Assembly success rate of 88%. One case of intraoperative brief temporary atrioventricular block, no other complications. Conclusion Accurate mapping target map is the premise of successful ablation. The right side of the bypass due to the particularity of the anatomy, the RFCA success rate is lower than the left.
