三维超声心动图左房自动定量技术及Simpson’s双平面法在心房颤动患者左房容积和功能检测中的参数比较

Parameters comparison of three-dimensional echocardiography left atrial automatic quantitative technique and Simpson’s biplane method in the determination of left atrial volume and function in patients with atrial fibrillation

目的比较三维超声心动图左房自动定量技术及Simpson’s双平面法在心房颤动(AF)患者左房容积和功能检测中的参数。方法选取2020年4月至12月云南大学附属医院收治的AF患者54例。三维超声心动图左房自动定量技术及Simpson’s双平面法获取左房最大容积(LAVmax)、左房最小容积(LAVmin)、左房收缩前容积(LAVpreA)、左房最大容积指数(LAVImax),左房总射血分数(LAEF)及分析时间;同时计算出左房主动射血分数(LAAEF)、左房被动射血分数(LAPEF)、左房扩张指数(LAEI);比较三维超声心动图左房自动定量技术及Simpson’s双平面法测量的观察者内及观察者间的一致性及重复性。结果AF患者三维超声心动图左房自动定量技术与Simpson’s双平面法测量的LAVmax、LAVmin、LAVpreA、LAVImax、LAEF、LAAEF、LAPEF、LAEI比较,差异无统计学意义(P>0.05)。三维左房自动定量技术分析时间短于Simpson’s双平面法(P<0.05)。三维超声心动图左房自动定量技术测量观察者内及观察者间的一致性及重复性优于Simpson’s双平面法。结论三维超声心动图左房自动定量技术能够准确评估AF患者左房容积及功能的变化,用时短,一致性和重复性更好。

Objective To compare the parameters of three-dimensional echocardiography left atrial automatic quantitative technique and Simpson’s biplane method in the determination of left atrial volume and function in patients with atrial fibrillation(AF).Methods A total of 54 AF patients admitted to Affiliated Hospital of Yunnan University from April to December 2020 were selected.Three-dimensional echocardiography left atrial automatic quantitative technique and Simpson’s biplane method were used to obtain left atrial maximum volume(LAVmax),left atrial minimum volume(LAVmin),left atrial pre-atrial contraction volume(LAVpreA),left atrial maximum volume index(LAVImax),left atrial total ejection fraction(LAEF),and the analysis time;at the same time,Left atrial active ejection fraction(LAAEF),left atrial passive ejection fraction(LAPEF),and left atrial expansion index(LAEI)were calculated;the consistency and repeatability of three-dimensional echocardiography left atrial automatic quantitative technique and Simpson’s biplane method were compared between intra-observer and inter-observer.Results There were no significant differences between LAVmax,LAVmin,LAVpreA,LAVImax,LAEF,LAAEF,LAPEF,and LAEI measured by three-dimensional echocardiography left atrial automatic quantitative technique and Simpson’s biplane method(P>0.05).The analysis time of three-dimensional echocardiography left atrium automatic quantitative technique was shorter than that of Simpson’s biplane method(P<0.05).The consistency and repeatability of the left atrial automatic quantitative technique of three-dimensional echocardiography left atrium automatic quantitative technique were better than those of Simpson’s biplane method in both intra-observer and inter-observer measurements.Conclusion Three-dimensional echocardiography left atrial automatic quantitative technique can accurately evaluate the changes of left atrial volume and function in patients with AF,with short time,better consistency and repeatability.
