title: Countercurrent arterial contrast echocardiography in the assessment of left to right ductal shunting in preterm infants.
abstract: A method of performing contrast echocardiography for the assessment of left to right ductal shunting in infants in a neonatal intensive care unit is described. Echo contrast was obtained by countercurrent injection of a small volume of blood through a radial artery canula . The technique was simple and reliable in 32 infants and no serious adverse reactions were observed.
