Measurements of the thickness of the septum were made in 26 cardiac specimens and in 13 patients. There were 10 normal specimens, five with aortic stenosis, two with asymmetric septal hypertrophy, four with hypertensive cardiovascular disease, and five with idiopathic cardiomyopathy. Patient measurements were obtained by visualizing the septum during simultaneous left and right ventriculography on angiograms obtained in the left anterior oblique projection. Four patients were normal, five had aortic stenosis, and four had a symmetric septal hypertrophy. Measurements derived from normal cardiac specimens and angiographic appearance suggested that the normal septum is a smooth-walled structure with right and left ventricular surfaces parallel, diverging only slightly at the apex of the ventricle. In aortic stenosis and idiopathic cardiomyopathy, the septum tends to be biconvex with maximal thickening in its middle third. Hypertensive cardiovascular disease produces uniform septal thickening, resembling an exaggeration of normal. However, in asymmetric septal hypertrophy no consistent patterns of hypertrophy or septal thickening are evident; bulging can be present at any point along the left ventricular surface of the septum.
对26个心脏标本和13名患者的室间隔厚度进行了测量。其中有10个正常标本，5个患有主动脉瓣狭窄，2个患有不对称性室间隔肥厚，4个患有高血压性心血管疾病，5个患有特发性心肌病。患者的测量是通过在左前斜位血管造影时同时进行左右心室造影来观察室间隔获得的。4名患者正常，5名患有主动脉瓣狭窄，4名患有对称性室间隔肥厚。来自正常心脏标本和血管造影表现的测量结果表明，正常室间隔是一个壁光滑的结构，其左右心室表面平行，仅在心室尖处略有分开。在主动脉瓣狭窄和特发性心肌病中，室间隔往往呈双凸形，在其中三分之一处增厚最大。高血压性心血管疾病导致室间隔均匀增厚，类似于正常情况的加剧。然而，在不对称性室间隔肥厚中，没有明显一致的肥厚模式或室间隔增厚；在室间隔左心室表面的任何一点都可能出现凸起。
