- Abstract
In order to obtain information useful for the diagnosis of fetus and newborn heart disease, we established a theoretical model of perinatal cardiac growth. We measured with the use of ultrasonic cross-section imaging system the mitral valve ring dimension, tricuspid valve ring dimension, and total cardiac dimension as morphological parameters of the heart in 45 cases composed of fetuses and children. The obtained data were entered into a computer. With the use of these data, simulation was made on the basis of the general theory of biological development. The present simulation showed that from the fetal stage to childhood the growth rates of the foregoing three morphological parameters mutually differ, but during the period of growth to the age of 12 years of the present study, they all demonstrated continuous growth up to 3 ½ years after birth when they reached a growth saturation level.
