三房心的影像学诊断（附九例报告）

Imaging Diagnosis of Cor Triatriatum(Report of 9 Cases)

本组９例三房心均经手术证实；其中４例术前经超声诊断，３例经心血管造影诊断。三房心的心血管造影表现为在侧位上相当于左房区域，有两个相邻的腔。根据显影的先后，确定副房和真房的位置。超声是诊断三房心的重要手段，对复杂病例仍应行心血管造影。

This article reported 9 cases of cor triatriatum all confirmed by operation,There were 4 cases diagnosed by echocardiography and 3 cases by angiocardiography before surgery.The lateral view of angiocardiography showed two adjacent chambers in the region of left atrium. The loca-tion of true chamber and accessory chamber were defined according to the time of opacification.Echocardiography is the imaging modality or choice in the diagnosis of this anomaly,however,angiocardiography is indicated in more complicated cases.
