摘要
目的:应用全容积三维超声(full volume three-dimensional echocardiography,FV3DE)技术评价房间隔缺损(atrialseptal defect,ASD)患者的心房容积和功能,以及ASD封堵术对心房容积和功能的影响。方法:应用FV3DE技术测量43例ASD患者及40例正常人的左、右心房的最小容积(Vmin)、最大容积(Vmax)及收缩前容积(Vp),并计算左、右心房传导功能和泵血功能。分别比较ASD组与正常组,ASD封堵前与术后结果。结果:ASD组右心房的心房最小容积(Vmin)、心房收缩前容量(Vp)、心房最大容积(Vmax)、心房主动收缩容积(Vae)、心房被动收缩容积(Vpe)、心房全部排空容积(Vte)均明显大于正常组(P<0.05),而心房被动收缩分数(Vpef)、心房主动收缩分数(Vaef)、心房全部排空分数(Vtef)明显小于正常组(P<0.05),封堵术后,右心房的Vmin、Vp、Vmax、Vae、Vaef、Vpe、Vte、Vtef均小于术前;左心房的Vp、Vmin、Vmax均大于术前,但Vaef、Vpef、Vte、Vtef较术前下降。结论:FV3DE能测量并评价ASD患者的心房容积和功能,ASD患者右心房的储蓄功能、管道功能增强,而泵血功能减低;ASD封堵术可使右心房容积得到纠正,左心房容积代偿性增加,介入手术操作及封堵器植入使管道功能和泵血功能均减低。
Objective: To quantify the volume and function of atrium in the patients with atrial septal defect(ASD) with full volume three-dimensional echocardiography(FV3DE) and evaluate the influence of occluder closure on the volume and function of atrium.Methods:FV3DE data of 43 patients with ASD and 40 normal controls were acquired and analyzed.Minimum volume(Vmin),maximum volume(Vmax) and pre-contraction volume(Vp) of atrium were measured,and the reservoir function,conduit function and pump function were calculated.All the results were compared respectively.Results:Vmin,Vp,Vmax,active emptying volume(Vae),passive emptying volume(Vpe)and total emptying volume(Vte)of right atrium in the patients with ASD were larger than those in the controls(P 〈 0.05);While passive emptying fraction(Vpef),active emptying fraction(Vaef) and total emptying fraction(Vtef)were smaller than those in the controls significantly(P 〈 0.05).After the occluder closure of ASD,the Vmin,Vp,Vmax,Vae,Vaef,Vpe,Vte and Vtef of right atrium became smaller,while Vp,Vmin,Vmax of left atrium became larger that before.And the Vaef,Vpef,Vte,Vtef of left atrium became smaller than those before operation.Conclusion:The atrial volume and function in the patients with ASD can be evaluated with FV3DE.As for the patients with ASD,reservoir function and conduit function of the right artrium increases and pump function decreases.After occluder closure,the volume of right atrium was retrieved,volume of left atrium enlarges for compensation,while the conduit function and pump function of both atria reduce.
