[Levogram in congenital cardiopathies. Its practical usefulness in newborn infants and small children given its low risk]. / El levograma en las cardiopatías congénitas. Su utilidad práctica en recién nacidos y niños pequeños por su bajo riesgo.

Four hundred and fifty six angiocardiograms were studied to evaluate the validity of levogram for diagnosis. They were separated in three groups: 1. Right angiocardiogram with a levogram. 2. Right angiocardiogram and left angiocardiogram. 3. Left angiocardiogram only. The distribution according to age, and type of heart disease is shown. The correlation between levogram and left angiocardiogram was looked for. The findings at survey were correlated with the angiocardiographic diagnosis and a high correlation was established. The usefulness of this procedure to diagnose specific type of heart disease in the small child is emphasized.
