心耳并列的超声心动图诊断价值

目的 探讨超声心动图诊断心耳并列的价值.方法 分析9例心耳并列患儿二维超声心动图表现,并与心血管造影、手术结果对比分析,总结其诊断要点.结果 9例心耳并列患儿中7例为心耳左侧并列,2例心耳右侧并列;均合并其他心脏复杂畸形,较为多见的是右室双出口、大动脉转位、单心室等.超声表现为于心底动脉短轴观直接观察到并列的心耳以及不正常横向的房间隔.超声诊断均与心血管造影、手术结果符合.结论 超声心动图诊断心耳并列具有较高的准确性,在复杂性先心病的诊断中应提高对本病的认识.

Echocardiographic diagnosis of juxtaposition of atrial appendage

Objective To study the value of echoeardiography for diagnosis of juxtaposition of atrial appendage(JAA) and to discuss its features. Methods Eehocardiographic characteristics of JAA in nine cases were compared with results of cardiac catheterization and operation. The diagnostic features of echocardiography were summarized. Results Seven cases had juxtaposition of left atrial appendage and two had juxtaposition of right atrial appendage. The nine cases were all associated with severe congenital heart disease and the most frequent malformations observed with JAA were double outlet right ventricle, transposition of great artery, single ventricle and so on. Direct visualization of the JAA in the parasternal short-axis view at the base of the heart and visualization of an unusual transverse orientation of the atrial septum were the most features of JAA. Echocardiographie characteristics of JAA cases were correspondent to the results of cardiac catheterization and operation. Conclusions There is high accuracy by echocardiography to diagnosis JAA. JAA should be alerted in severe congenital heart disease.
