Eigenvolumes calculated from a linear transformation model were found previously to be linearly related to balloon volumes in excised hearts. The present study analyzed endocardial marker kinematics in intact, contracting left ventricles by biplane cinefluorography. Ejection fractions of the linear transformation model were compared by linear regression analysis with those of an ellipsoidal model, whose ejection fractions had been documented previously in closed and open-chest dog preparations. Data from 10 dogs indicated a correlation coefficient of 0.98 and a regression equation with close similarity to the line of identity. Ejection fractions calculated from the linear transformation model are concluded to be proportional to actual ejection fractions in intact, beating left ventricles.
