阜外贾玉和等研究称,心腔内三维超声辅助房颤射频消融安全可行

2020-03-06 xunhuan 中国循环杂志

经导管射频消融已成为阵发性房颤和持续性房颤的一线治疗方法。常规射频消融使用的导管需要使用造影剂及X 线进行定位和引导。阜外医院贾玉和、孙丽娜等发表研究称,对于伴造影剂不相容的心房颤动患者,心腔内三维超声可以替代经食道超声心动图声辅助房颤射频消融。而且心腔内三维超声不延长手术时间,显着减少X 线曝光时间及剂量,可避免穿刺房间隔的并发症,提高穿刺准确性。研究选择2015 年1 月至2017 年1 月期

经导管射频消融已成为阵发性房颤和持续性房颤的一线治疗方法。常规射频消融使用的导管需要使用造影剂及X 线进行定位和引导。

阜外医院贾玉和、孙丽娜等发表研究称,对于伴造影剂不相容的心房颤动患者,心腔内三维超声可以替代经食道超声心动图声辅助房颤射频消融。

而且心腔内三维超声不延长手术时间,显着减少X 线曝光时间及剂量,可避免穿刺房间隔的并发症,提高穿刺准确性。

研究选择2015 年1 月至2017 年1 月期间中国医学科学院阜外医院收治的16 例心房颤动伴造影剂不相容的患者。

患者均未行左心房、肺静脉CT 和造影,在心腔内三维超声辅助下建立左心房及肺静脉三维模型,并指导穿刺房间隔和消融导管在心脏内的操作。

15 例患者顺利完成心房颤动射频消融,平均手术时间(96.0±14.3) min,透视时间(6.1±1.2) min,X 线透视剂量(115.8±49.3) mGy,未发生心脏压塞、脑栓塞、左心房- 食道瘘、肺静脉狭窄及动脉瘤等并发症及死亡。

1年随访结果显示,9 例患者维持窦性心律,其中阵发性心房颤动7 例,持续性心房颤动2 例。

研究者认为,对于一些特殊房颤患者的射频消融,如造影剂不相容、结构明显变异、房间隔穿刺风险大(房间隔瘤),或许适合心腔内三维超声辅助。
