Patent ductus arteriosus in infancy

Abstract

The findings in 28 infants in whom a patent ductus arteriosus was the sole cardiac abnormality are reviewed in an attempt to define the clinical features in infancy and to assess the value of routine radiography and electrocardiography. The different clinical findings in small and large patent ducts are illustrated and the similarity of this lesion to some cases of persistent truncus arteriosus in the early months of life is described. The pitfalls caused by an overcompensating ductus are discussed. The indications for cardiac catheterization and angiocardiography and their value in differential diagnosis are also considered. The problems of surgical treatment are mentioned.
