Abstract
results: MR jet geometry was classified into the following 3 categories: a curtain-like jet along almost the entire mitral leaflet coaptation (30 pts), a central jet from the central leaflet coaptation area (25 pts), and two separate jets (10 pts; Figure A-C). No difference in mitral annular area was found between the three groups. Pts with a central jet had smaller coaptation distance and tenting area at medial and lateral (all p<0.01) than those with a curtain-like jet, whereas no differences in these parameters at central area between the two groups. Compared to pts without two separate jets, those with two separate jets had similar coaptation distance and tenting area. However, pts with two separate jets had greater coaptation length (overlap length of the anterior and posterior leaflet) at the central area than those with a curtain-like jet and a central jet (4.5±0.5 vs. 3.6±1.1, 4.5±0.5 vs. 3.4±0.7 mm, respectively, both p<0.001).
