If it's a small VSD, it might be asymptomatic.

如果室间隔缺损较小，可能无症状。

HOCM, VSD, a sclerosis, aortic flow murmur, at least the medical students' final level.

HOCM，VSD，硬化症，主动脉血流杂音，至少这是医学生最后一年的水平。

Due to the severity of these complications with larger defects, surgical closure of the VSD might be needed.

更大的缺损会导致这些并发症更严重，就需要行手术关闭室间隔缺损。

As the size of the VSD increases, though, symptoms tend to get more severe and present earlier on in life.

然而，室间隔缺损越大，症状一般会越严重，并且更早出现。

Also, that blood flowing through a VSD can be heard as a holosystolic murmur at the lower left sternal border.

并且，血液流经VSD时，在左下胸骨边缘听诊就会听到全收缩期杂音。

If these don't fuse though, then a gap is left between the two chambers, in other words, a ventricular septal defect, or VSD.

如果这些组织不能融合起来，就会在两个心腔之间留有一个缺口，也就是室间隔缺损，简称VSD。

If pressure increases to a point where the right side's more than the left side, then the direction of blood flow through the VSD can switch from being left-to-right to right-to-left, a condition known as Eisenmenger syndrome.

如果压力一直上升到心脏右侧比左侧还高，那么VSD的血流方向就会从左向右切换到右向左，这种疾病被称为艾森曼格综合症。
