In order to assess the functioning of the pivoting disc of the Lillehei-Kaster prosthetic valve, a cinefluoroscopic technique using multiple angulations was developed. The disc was detected in 240 (99%) of the 242 valves studied (126 aortic, 107 mitral, and nine tricuspid valves). The maximal-opening angle of the disc was measured in 75% of the aortic but only 20% of the mitral valve prostheses in the 182 valve studies in which this was attempted. Prosthetic dysfunctions were suspected clinically in three aortic and three tricuspid valves and confirmed with the cinefluoroscopic technique. This cinefluoroscopic approach constitutes a rapid, noninvasive, and sensitive evaluation of the function of the Lillehei-Kaster prosthetic valve in the aortic position.
为评估 Lillehei-Kaster 人工瓣膜旋转盘的功能，开发了一种使用多个角度的电影荧光镜检查技术。在所研究的 242 个瓣膜（126 个主动脉瓣、107 个二尖瓣和 9 个三尖瓣）中，在 240 个（99%）瓣膜中检测到了旋转盘。在 182 次瓣膜研究中，尝试测量了 75% 的主动脉瓣人工瓣膜旋转盘的最大开口角度，但二尖瓣人工瓣膜仅测量了 20%。临床上怀疑 3 个主动脉瓣和 3 个三尖瓣人工瓣膜存在功能障碍，并通过电影荧光镜检查技术得到证实。这种电影荧光镜检查方法对主动脉位置的 Lillehei-Kaster 人工瓣膜功能构成了快速、无创且敏感的评估。
