Results
Some degree of asymmetry was present in all analyzed valves. Absolute
and relative differences for free margin length were 3.2 ± 1.4 mm and
9.3 ± 3.8%, respectively. The largest relative difference was noted in
coaptation area (36.5 ± 16.5%) and the smallest in leaflet effective
height (6.1 ± 4.8%). Using predefined cut-off criteria for absolute
differences in leaflet dimensions, 86% of the valves were classified as
asymmetric.
