Fig 1 Schematic representation of the mitral and aortic annular marker arrays used in the study. (AML = anterior mitral leaflet; L = left aortic cusp; LFT = left fibrous trigone; NC = noncoronary aortic cusp; PML = posterior mitral leaflet; R = right aortic cusp; RFT = right fibrous trigone.)

Fig 2 Group mean mitral annular area (solid squares), aortic annular area (open squares), and left ventricular pressure (LVP solid line) throughout the cardiac cycle for 7 animals at baseline. A 650 ms time window centered at end diastole (ED) (dashed vertical line at t = 0) is illustrated for all variables. Error bars indicate one standard error of the mean. (LVP= left ventricular pressure.) The Annals of Thoracic Surgery 2003 76, 1944-1950DOI: (10.1016/S0003-4975(03)01078-6)

Fig 3 Group mean total annular circumference (top), fibrous annulus length (middle), and muscular annulus length (bottom) for mitral annulus (solid squares), and aortic annulus (open squares) throughout the cardiac cycle for 7 animals at baseline. Left ventricular pressure (LVP) tracing (solid line) is shown in each panel. A 650 ms time window centered at end diastole (ED) (dashed vertical line at t = 0) is illustrated for all variables. Error bars indicate 1 standard error of the mean. The Annals of Thoracic Surgery 2003 76, 1944-1950DOI: (10.1016/S0003-4975(03)01078-6)

Fig 4 Group mean aorto-mitral angle (solid squares), left ventricular pressure (LVP) (solid line), and left ventricular (LV) volume (dashed line) throughout the cardiac cycle for 7 animals at baseline.
