彩色多普勒超声心动图对三房心的诊断价值

目的　评价彩色多普勒超声心动图 (CDE)对三房心的诊断价值。方法　应用CDE检查了 5例三房心患者 ,并与手术结果对照。结果　完全三房心 3例 ,部分三房心 1例 ,右心三房心 1例。其中 2例分别伴有房间隔缺损和部分肺静脉异位引流。术前超声提示三房心 4例 ,漏诊 1例 ,心内其他异常均诊断正确。结论　依据 2DE显示心房内异常隔膜 ,CD FI检测到房水平分流或副房与真房间有射流 ,即可确诊为三房心 ,因此 ,CDE是诊断三房心的首选方法

The Diagnostic Value of Color Doppler Echocardiography on Cor Triatrium

Objective To evaluate the diagnostic value of color doppler echocardiography in cor triatrium. Methods Five cor triatrium patients were examined with CDE, the results were compared with the surgical findings. Results Three cases absolute cor triatrium, one case partial cor triatrium and one case cor triatrium of right heart. Two patients accompanied with ASD and PAPVC among the five patients. Four cor triatrium were preoperatively discovered by echocardiography, while one was missed. The diagnoses of all the other cardiac abnormalities were correct. Conclusion The diagnostic key of cor triatrium was to find a membrane in atrium on 2 DE and a shunt at the level of atrium or a jet between real atrium and subatrium demonstrated on CDFI. Therefore, CDE is the first method in the diagnosis.
