Abstract

Morphometric measurements of 22 hearts with total anomalous pulmonary venous connection (TAPVC) were compared with measurements of 8 matched control specimens without heart disease. Each of the TAPVC specimens had a shorter left atrium, smaller left atrial surface area and larger diameter of the fossa ovalis. In addition to increased length of the right ventricle and larger circumferences for tricuspid and pulmonary valve anuli, the left ventricular contour of the ventricular septum was flat or convex in 18 of the 22 hearts; the septum was significantly longer than normal in these specimens and wider at its midportion. Because mitral and aortic valve anuli were normal in circumference, the data suggest that left ventricular volume is not decreased despite change in ventricular shape.

摘要

对22例完全性肺静脉异位连接（TAPVC）心脏的形态学测量结果与8例无心脏病的匹配对照标本的测量结果进行了比较。每例TAPVC标本的左心房较短，左心房表面积较小，卵圆窝直径较大。除右心室长度增加以及三尖瓣和肺动脉瓣环周长增大外，22例心脏中有18例的室间隔左心室轮廓平坦或凸出；这些标本中的室间隔明显比正常长，且中部更宽。由于二尖瓣和主动脉瓣环周长正常，数据表明尽管心室形状改变，但左心室容积并未减少。
