Concentric hypertrophy leading to diastolic failure can also be caused by aortic stenosis, which is a narrowing of the aortic valve opening, as well by hypertrophic cardiomyopathy, an abnormal ventricular wall thickening often from a genetic cause.

导致舒张性心衰的向心性肥大，也可能由主动脉瓣狭窄（即主动脉瓣开口变窄）造成，也可能由肥厚型心肌病（一种遗传性异常心室壁增厚）引起。

Number two is I wanna learn all the terms. If there's a certain term in the lecture that I don't understand, like for example, hypertrophic cardiomyopathy, I wanna look it up so I know what that term means.

第二是我想学习所有的术语。 如果讲座中有某个术语我不明白，例如，肥厚性心肌病， 我想查一下， 这样我就知道那个术语的意思了。
