Again the sub endocardial region seems to be the most precarious in terms of blood supply.

同样，内膜下区域似乎是最不稳定血液供应。

In this case, eosinophils accumulate in the endocardial layer of the heart tissue, causing inflammation and endocardial fibrosis, making it stiffer and again less compliant.

在这类病例中，嗜酸性粒细胞聚集在脏内膜层，导致炎症和内膜纤维化，让其更加、应性更差。

Yet another is endocardial fibroelastosis, where fibrosis develops in the endocardium, the inner lining of the heart, as well as the subendocardium right under, again making the tissue less compliant.

还有另一种病因是内膜弹力纤维增生症，即在内膜以及内膜下层发生了纤维化，使得脏应性变差。

The septum is formed during development as this muscular ridge of tissue grows upward from the apex, or the tip, and then fuses with a thinner membranous region coming down from the endocardial cushions.

室间隔在胚胎发育期间形成，这种肌肉嵴从尖部往上长，并与从内膜垫向下延伸薄膜区域融合。

Ischemia in the areas supplied by the partially occluded vessel illustrated here in the lateral wall of the left ventricle is primarily targeted on the sub endocardial aspect of the affected region.

左室侧壁部分闭塞血管供应区缺血主要是针对受影响区内膜下。
