| 摘 要： | 目的研究食道超声心动图(TEE)在左侧和右侧房室旁路射频消融术中(RFCA)监测的意义。方法对31例房室旁路患者进行RFCA术的TEE检查。结果RFCA术全部成功。TEE食道留置时间为35±11min。TEE导引了全部患者的消融电极的放置和位置调整，诊断器质性病变3例，导引穿房间隔术和穿隔后的电极放置3例，发现2例消融过程中出现中度二尖瓣返流，及时调整消融电极位置后消失。结论在RFCA术中行TEE监测有助于电极的定位和防止电极脱位，及时发现并发症，以及导引冠状窦电极放置和穿房间隔消融。

| Abstract: | Objective: To evaluate the role of transesophageal echocardiography (TEE) in monitoring patients during radiofrequency catheter ablation (RFCA). Methods: Thirty one RFCA procedures were performed in 25 patients with left side accessory pathway and 4 patients with right side accessory pathway. Under local lidocain gel anesthesia, all patients were monitored during RFCA with TEE. Results: TEE was used to detect underlying heart diseases in 3 patients, guide transseptal catheterization in 3, and find transient moderate mitral regrugitation in 2 during RFCA. It helped position the RFCA catheter's tip, and evaluate for possible complications in all patients.Conclusion: This study suggestes that TEE might be useful in RFCA procedures under local anesthesia. |
