Calculated radius using the triangulation method (<i>R</i>) along with the radii calculated from the area (<i>R</i>_<i>A</i>) and circumference (<i>R</i>_<i>C</i>), using the assumption of flat annuli, at minimum and maximum right ventricular pressure (RVP) for intact and post chordae rupture (PCR) conditions.

The values are presented for all eight experimental hearts along with the average (AVG) and standard deviation (STD). Comparison between R, RA, and RC showed that the three different methods of calculating the radius produced the same results.
