Posterior leaflet angle with annulus (α2, degrees)	58.6 ± 21.5	72.2 ± 35.0	0.32
Anterior leaflet curvature (β, degrees)	145 ± 11	150 ± 9.0	0.14
Mitral annular dynamics
Mitral annular area (systolic, cm²)	7.0 ± 1.5	3.7 ± 1.2	0.01
Mitral annular systolic contraction (%)	13.1 ± 11.2	13.3 ± 7.2	0.98
Annular height to commissure width ratio (%)	27.0 ± 2.2	36.8 ± 3.9	0.02
