Angiocardiography from an umbilical vessel approach was performed in 10 critically sick newborn infants. The umbilical vein route was successfully employed up to the eighth day of life, while the umbilical artery was safely used as late as age 5 days. This approach has advantages over other methods of catheterization and angiocardiography. Angiocardiographic quality was satisfactory for accurate interpretation.
