Angiocardiographic estimation of left ventricular mass in normal infants and children.
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) g (r = 0.98, p less than 0.01), left ventricular mass-posterior = 84.6 (body surface area) g (r = 0.97, p less than 0.01). Left ventricular mass-anterior/left ventricular end-diastolic volume averaged 0.73 +/- 0.01 g/ml, and left ventricular mass-posterior/left ventricular end-diastolic volume 0.89 +/- 0.02 g/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.
