The Bjork-Shiley prosthesis has been used extensively for valvular replacement since 1969. Despite its widespread use, it is subject to complications that can be assessed with cineradiography. New methods are presented for assessment of incomplete closing and opening angles that occur with valvular malfunction. Alternative methods of cineradiographic measurement are compared with each other and with the new method. The new method is an appropriate alternative when the conventional double-profile method cannot be used and distributes the burden of performance and complexity between the technologist and radiologist. This new method is shown to be accurate to within 1 degree.
自1969年以来，Bjork-Shiley人工心脏瓣膜已被广泛用于瓣膜置换。尽管其使用广泛，但仍会出现一些并发症，这些并发症可通过电影血管造影术进行评估。本文介绍了评估瓣膜功能异常时出现的不完全关闭和开放角度的新方法。将电影血管造影测量的替代方法相互比较，并与新方法进行比较。当传统的双轮廓方法无法使用时，新方法是一种合适的替代方法，它将操作负担和复杂性在技术人员和放射科医生之间进行了分配。结果表明，这种新方法的准确度在1度以内。
