Figure 6 A linear correlation was demonstrated between the occlusional leaflet area (OLA) and regurgitant fraction (RF) (dependent variables) and the total chordal netforces,  [FC – FT]S (independent variable). Data represent one valve at all test conditions. Trends are representative of all valves (compare with Table 3). Solid circles = HR: 70; LVP – LAP: 90; solid squares = HR: 120; LVP – LAP: 90; open circles: HR: 70; LVP – LAP: 150; open squares = HR: 120; LVP – LAP: 150. HR = heart rate; LVP – LAP = transmitral pressure difference.
