Between the years 1954 and 1958, the combined effort of a surgeon and an engineer allowed the development of some of the principles of aortic valve construction that proved clinically successful several years later. It was demonstrated for the first time that there was adequate room in the area of the sinuses of Valsalva below the coronary arteries for a prosthetic ball valve, and that such a ball valve did not obstruct flow. Aortic pulse tracings with such a ball valve in place were indistinguishable from those with the natural valve. Finally, the principle of the cloth sewing ring was utilized for suturing the valve in place.
在1954年至1958年期间，一位外科医生和一位工程师共同努力，促成了一些主动脉瓣构造原理的发展，这些原理在数年后被证明在临床上是成功的。首次证明，在冠状动脉下方的主动脉窦区域有足够空间容纳人工球瓣，且这种球瓣不会阻碍血流。安装了这种球瓣的主动脉脉搏描记图与天然瓣膜的脉搏描记图无法区分。最后，采用了布质缝合环的原理将瓣膜缝合到位。
