A defective aortic valve removed from a cadaver was installed on a testing unit imitating systemic circulation. The defect (insufficiency of the valve) was corrected by means of valvular devices consisting of a thin elastic membrane which was flat and round in one case and shaped like a spherical vault in the other; the devices were fastened on the distal end of a catheter. The authors present the values of pressure in the heart, aorta and coronary arteries and the minute circulation volume before and after correction of the defect. It is concluded that the suggested valvular devices are efficient and further study is expedient.
从一具尸体上取下的有缺陷的主动脉瓣被安装在一个模拟体循环的测试装置上。通过由薄弹性膜组成的瓣膜装置来纠正缺陷（瓣膜功能不全），在一种情况下，该弹性膜是扁平圆形的，在另一种情况下则呈球形拱顶状；这些装置固定在导管的远端。作者给出了缺陷纠正前后心脏、主动脉和冠状动脉中的压力值以及每分钟循环血量。得出的结论是，所建议的瓣膜装置是有效的，进一步的研究是适宜的。
