摘要
以单导管法对3例体表心电图有delta波的预激综合征患者行射频消蚀。据心电图定位旁路后,将一根消蚀导管经右股动脉插入左室,在二尖瓣环左室侧标测到旁路电位后以该导管放电,全部成功。平均放电5次,平均操作时程1.3小时。本观察提示,单导管是消蚀部分显性预激患者房室旁路的简便、安全和有效的方法。
Three patients with Wolff-Parkinson-White syndrome and a delta wave pattern indicative of an overt left-sided free wall accessory pathways undewent radiofrequency ablation with the use of only one catheter. No patient had a previous electrophysiological study. The catheter was introduced into the left ventricule close to the mitral annulus and was used for mapping as well as for ablation. The approach was completely successful in all the patients after the procedure. Overall procedure duration was 1.3 hours, there were no acute complications. The tachycardia did not reccur after 2 months follow-up. Thus, the single-catheter approach is feasible, safe and effective for the patients with overt left-sided accessory pathways.
