经食道超声心动图在卵圆孔未闭合并房颤患者左心耳容积和功能改变评估中的应用

Application of transesophageal echocardiography in the assessment of left atrial ear volume and function changes in patients with patent foramen ovale and atrial fibrillation

目的 探讨经食道超声心动图在卵圆孔未闭合并房颤患者左心耳容积和功能改变评价中的应用价值。方法 选取卵圆孔未闭患者80例为研究对象,根据是否合并房颤分为房颤组(n=44)和非房颤组(n=36),另选取同期检查的健康者30例作为对照组。3组行经食道超声心动图检查。比较3组左心耳容积及功能变化情况。结果 房颤组及非房颤组患者左心耳最大容积(LAAV_(max))、左心耳最小容积(LAAV_(min))、左心耳开口最大面积(MA)、左心耳开口最大长径(MD)大于对照组,左心耳最大排空速度(LAAeV)及左心耳最大充盈速度(LAAfV)小于对照组,差异有统计学意义(P<0.05)。房颤组左心耳自发显影(SEC)患者的LAAV_(max)、LAAV_(min)、左心耳开口MA、左心耳开口MD大于非房颤组,LAAeV及LAAfV小于非房颤组,差异有统计学意义(P<0.05)。治疗后,房颤组的终点事件发生率高于非房颤组,差异有统计学意义(P<0.05)。结论 经食道超声心动图在卵圆孔未闭合并房颤患者左心耳容积和功能改变评价中的应用效果较好。合并房颤患者的左心耳功能较未合并房颤患者差。

Objective To investigate the application of transesophageal echocardiography in the evaluation of left atrial ear volume and function changes in patients with patent foramen ovale and atrial fibrillation.Methods Eighty patients with patent foramen ovale were selected as the study objects,and were divided into atrial fibrillation group(n=44)and non-atrial fibrillation group(n=36),and 30 healthy subjects were selected as control group.Transesophageal echocardiography was performed in three groups.The left atrial appendage volume and changes of function in three groups were compared.Results The left atrial appendage _(max)imum volume(LAAV _(max)),left atrial appendage _(min)imum volume(LAAV _(min)),left atrial appendage opening _(max)imum area(MA)and left atrial appendage opening _(max)imum length diameter(MD)in the atrial fibrillation group and non-atrial fibrillation group were significantly higher,and the left atrial appendage _(max)imum emptying velocity(LAAeV)and left atrial appendage _(max)imum filling velocity(LAAfV)were significantly lower than those of the control group(P<0.05).The LAAV _(max),LAAV _(min) as well as MA and MD of left auricular opening in patients with left auricular spontaneous imaging(SEC)in the atrial fibrillation group were significantly higher than those in the non-atrial fibrillation group,and LAAeV and LAAfV were significantly lower than those in the non-atrial fibrillation group(P<0.05).After treatment,the incidence of end-point events in the atrial fibrillation was significantly higher than that in the non-atrial fibrillation group(P<0.05).Conclusion The application of transesophageal echocardiography in the evaluation of left atrial ear volume and function changes in patients with patent foramen ovale and atrial fibrillation is effective.The left atrial appendage function of patients with atrial fibrillation is worse than that of patients without atrial fibrillation.
