Flail Width, Flail Gap, Posterior Leaflet Length, Leaflet
Thickness, Cleft Leaflet
In cases of flail pathology, there was no statistical difference between
flail width measurements (10.9 +/- 3.22mm vs 8.7 +/- 3.18mm, P= 0.14).
However, MDCT over-estimated the flail gap measurement (3.6+/- 3.3mm vs
8.1 +/- 2.01mm, P=0.023). Similar measurements were obtained for
posterior leaflet length (13.24 +/- 3.2mm vs 13.46+/- 2.43mm, P=0.77)
and leaflet thickness (2.1 +/- 0.7mm vs 1.96 +/- 0.551, P=0.36). There
were two cases of cleft leaflet and MDCT was unable to detect a cleft
leaflet in 1 of the patients.
