Leaflet Location
MDCT correctly predicted the dysfunctional leaflet location 95% (21/22) of the time. There were 3 cases in which degenerative dysfunction occurred in more than one location. MDCT was able to determine the major dysfunction (flail) in each of them but did not to pick up the secondary area of degeneration. In one patient with a functional MR, it appeared that there was prolapse of one segment on MDCT. In combination, MDCT was able to correctly identify the leaflet pathology and location in 77% (17/22) of patients.
