他の心疾患のために施行したカラードプラ心エコー図にて偶然に心房中隔を通過する血流が見られ,心臓カテーテル検査で心房中隔欠損症を確認しえた2例を経験した.心放射図では少量の左右シャントパターンがみられたが,理学的所見,心電図,胸部X線,断層心エコー図は正常であった.カラードプラ心エコー図は心房中隔欠損部を通過する血流が観察できるため心房中隔欠損症の診断には鋭敏すぎる.しかし,他の診断法で心房中隔欠損症が検出できないものはいわゆる,“ドプラ弁膜症”と同様に臨床的意義は少ないと思われた.
We describe two cases of atrial septal defect (ASD) diagnosed by chance with two-dimensional Doppler echocardiography (2DD) which was carried out for another purpose.
There were no findings characteristic of ASD such as systolic murmurs in the pulmonary area, incomplete right bundle branch block pattern on electrocardio-grams, increased hilar shadow on chest films or in-creased right ventricular chamber diameter in two-dimensional echocardiography. However, the 2DD showed blood flow crossing through the atrial septum. Cardiac catheterization confirmed the presence of a small ASD.
