This study comprises 83 patients who underwent surgery for atrial septal defect of secundum type (ASD II) after 40 yr of age. A follow-up study was performed on average 74 mth after surgery. Before surgery enlarged heart volume was found in 72% of the patients. Increased pulmonary vascularity was the most characteristic finding (96%), followed by enlarged central hilar vessels. The heart volumes showed best correlation with the right ventricular systolic pressure, whereas correlation with the shunt ratio was much poorer. After surgery the mean heart volume was reduced by 22% in patients who were without a residual shunt. In only one of these the volume was increased. The pulmonary vascularity remained increased in 30% after surgery. In patients with a residual shunt, the frequency of still enlarged or increased heart volume, and increased pulmonary vascularity, was considerably large than in patients with completely closed ASD.
本研究纳入了83例40岁以后接受继发孔型房间隔缺损（ASD II）手术的患者。术后平均74个月进行了随访研究。术前，72%的患者发现心脏体积增大。肺血管增多是最典型的表现（96%），其次是中央肺门血管增粗。心脏体积与右心室收缩压的相关性最佳，而与分流比的相关性则差得多。术后，无残余分流的患者平均心脏体积减少了22%。其中只有1例体积增大。术后30%的患者肺血管仍增多。有残余分流的患者中，心脏体积仍增大或增加以及肺血管增多的发生率明显高于ASD完全闭合的患者。
