AKIBA, T., YOSHIKAWA, M., OTAKI, S., KOBAYASHI, Y., NAKASATO, M., SUZUKI, H. and SATO, T. Angiocardiographic Estimation of Left Ventricular Mass in Normal Infants and Children. Tohoku J. exp. Med., 1986, 150 (3), 299-307-Left ventricular mass data were obtained from biplane cineangiocardiograms in 37 normal infants and children. Left ventricular mass calculated by using thickness of anterior wall (left ventricular mass-anterior) and posterior wall (left ventricular mass-posterior) of the free left ventricular wall were studied in relation to body surface area and left ventricular end-diastolic volume. Both of left ventricular mass-anterior and mass-posterior were expressed as a function of body surface area with exponential relationship ; left ventricular mass-anterior=68.5 (body surface area)1.46g (r=0.98, p<0.01), left ventricular mass-posterior=84.6 (body surface area)1.54g (r-0.97, p<0.01). Left ventricular mass-anterior/left ventricular end-diastolic volume averaged 0.73±0.01g/ml, and left ventricular mass-posterior/left ventricular end-diastolic volume 0.89±0.02g/ml, respectively. Thus, left ventricular mass can be predicted from body surface area by using the exponential equations. In addition, normal values for left ventricular mass- posterior must be discriminated from those for left ventricular mass-anterior.
