[Unidimensional echocardiogram of normal infants and children (author's transl)]. / L'échocardiogramme de l'enfant normal. Les paramètres de la fonction ventriculaire gauche.

ABSTRACT

One hundred and one echocardiograms were performed in children 8 days to 15 years old. The values measured were end-diastolic and end-systolic left ventricular diameters, aortic root diameter, left atrial diameter, end-diastolic septal and posterior wall thickness, mitral valve excursion. There is a good correlation of these values with the square root surface area. The indices of left ventricular performance are mean velocity of circumferential fiber shortening (correlated with heart rate), ejection fraction and shortening fraction. These indices are not correlated with body surface area. These data can be used in the echocardiographic investigation of infants or children with heart diseases.
