实时三维经食管超声心动图在卵圆孔未闭封堵术中的独特优势
Journal of Medical Imaging(2022)
Abstract
目的 探讨实时三维经食管超声心动图(real-time three-dimensional transesophageal echocardiography,RT3D-TEE)在经导管卵圆孔未闭(patent foramen ovale,PFO)封堵术中的应用价值.方法 选取应用RT3D-TEE检查的104例PFO的解剖形态及周围结构,对比2D-TEE测量PFO大小和2D-TEE切面下封堵过程中、封堵器释放后导管及封堵器伪像发生率,分析RT3D-TEE在PFO封堵中的独特优势.结果 RT3D-TEE测量PFO最大宽度较常规2D-TEE较大,差异有统计学意义,P<0.05;104例患者中22例(21.2%)在2D-TEE切面左心房内有导管伪像出现,24例(23.4%)封堵器在房间隔同侧出现伪像;RT3D-TE引导下97例(93.3%)封堵成功,6例失败改经胸小切口封堵,1例塑形不佳.结论 RT3D-TEE较2D-TEE有其独特的优势,在经导管PFO封堵治疗中有不可替代的作用.
