A 67-year-old woman who had undergone aortic and mitral valve replacement 15 years previously, was admitted to the authors’ hospital with congestive heart failure. No transthoracic echocardiography findings indicative of prosthetic valvar failure were detectable. However, coronary computed tomographic angiography revealed a tiny pocketlike pannus or thrombus around the pivot of the aortic prosthesis, which could obstruct motion of the pivot. Using volume-rendered imaging, the optimal angulation of the image intensifier for tangentially evaluating the bileaflet aortic valvar motion was simulated. Subsequently, the

patient underwent cinefluoroscopic evaluation from the simulated direction, which clearly confirmed the stuck aortic valve.

Video 1: Cinefluoroscopy as viewed from the left anterior oblique angle of 15°. The bileaflet aortic prosthetic valve was viewed tangentially as simulated in Fig. 1F, whereas a nearly en-face view of the mitral prosthetic valve was observed. Note the significant opening restriction of the aortic prosthetic valve.
