Mitral regurgitation is associated with leaflet thickening and increased tenting area in patients with IMR. (A) Anterior and posterior mitral valve leaflet thickness were measured in the middle portion of the leaflet (left: bidirectional red arrows). Tenting area was measured as the area surrounded by leaflets and the line between annuluses on apical 3ch-view in mid-systole (middle: yellow area). Vena contracta (VC) width was measured as the narrowest width of mitral regurgitation jet (right: bidirectional yellow arrow). Comparison of VC (B), anterior leaflet thickness (C), anterior leaflet length (D), tenting area (E) between patients presenting moderately severe MR (MSMR) (n = 11) and severe MR (SMR) (n = 6). Linear correlation between VC and anterior leaflet thickness (F), tenting area (G), anterior leaflet length (D) and age (H). (I) VC in female (n = 7) and male (n = 10). LA, left atrium; LV, left ventricle; AL, anterior mitral valve leaflet; PL, posterior mitral valve leaflet. ns, no-significant, ***p < 0.001. Thin dotted line shows the 95% confidence interval.
