The results of cinefluoroscopic evaluation in 509 patients in whom there was no evidence of prosthetic mitral or aortic valve regurgitation were compared with those in 41 patients who had perivalvular aortic or mitral regurgitation. Rotational motion of the base ring of each prosthesis (base-ring tilt) was measured in at least two views. A base-ring tilt of 7 degrees or more for aortic prostheses or 11 degrees or more for mitral prostheses was associated with an increased incidence of significant perivalvular regurgitation. Likewise, in patients who had multiple studies, a change between studies in base-ring tilt of 4 degrees or more for aortic prostheses or 5 degrees or more for mitral prostheses was associated with significant perivalvular regurgitation. These data suggest that the presence of either an abnormal base-ring tilt or an abnormal increase in base-ring tilt is strong, supportive evidence of partial prosthetic valve dehiscence.
