摘要
目的 :以经胸壁超声心动图(TTE)为标准,探讨双源CT(DSCT)评价复杂先天性心脏病(CCHD)患者左心室功能的价值。方法:经临床和超声诊断的CCHD 27例,行DSCT和TTE测量左心室功能各参数。DSCT左心室功能测量由2名影像诊断医师进行。比较DSCT和TTE所测得左心室功能各参数,分析DSCT不同测量者所得参数的一致性。结果:DSCT测量的左心室功能各指标:舒张末期容积(EDV)、收缩末期容积(ESV)、每搏输出量(SV)、射血分数(EF)与TTE测量比较,差异均无统计学意义(均P>0.05)。DSCT不同测量者间测量值的差异无统计学意义(P>0.05),可重复性好。结论 :DSCT评价CCHD患者左心室功能准确、可靠、可重复性好,可为临床术前评估、制订手术方案及判断预后提供参考。
Objective：To evaluate the clinical value assessing left ventricular function in patients with complex congenital heart disease （CCHD） using dual-source computed tomography （DSCT） with transthoracic echocardiography （TTE） as standard of reference. Methods：27 patients with complex congenital heart disease （CCHD） were diagnosed by clinic and TIE.Measured and compared parameters of left ventricular function of the patients using DSCT and TIE. And two radiologists measured left ventricular function parameters of DSCT. Compared the parameters measured by two radiologists. Results：The end diastolic volume （EDV）,end systolic volume （ESV）,stroke volume （SV）,ejection fraction （EF） measured by DSCT were higher than those by TIE,no significant difference was found among the measurements between DSCT and TrE. No significant difference was found among the measurements between different measurer （P〉0.05）. Conclusions：DSCT is an accurate,feasible and good repeatability method to assess the left ventricular function of CCHD. It has great value for DSCT to estimate before surgery,decide surgical strategy and evaluate the effectiveness of the therapy.
