Fig. 1From: Three-dimensional analysis of the tricuspid annular geometry in healthy subjects and in patients with different grades of functional tricuspid regurgitationTricuspid valve (TV) dimensions representing three-dimensional valve geometry at the referent frame in mid-systole. A dimensions of tricuspid annulus (TA): TA area- yellow area, TA perimeter- blue contour, 4Ch diameter- dark green line, 2Ch diameter- bright green light, major axis- dark pink line, minor axis- bright pink line. B dimensions of leaflet tethering: tenting volume- yellow surface, max tenting height- yellow line, coaptation point height- red line. Green, brown, purple, and yellow points marks are the anterior, free wall, posterior and septal edges of TABack to article page
