Percutaneous angiocardiography for diagnosis of persistent ductus arteriosus in the preterm infant.

Development of a Diagnostic Clinical Score for Hemodynamically Significant Patent Ductus Arteriosus

There is no consensus about the hemodynamic significance and, therefore, the need to treat a persistent ductus arteriosus in preterm newborns. Since the diagnosis of a hemodynamically significant persistent ductus arteriosus (hsPDA) is made by a summary of non-uniform echo-criteria in combination with the clinical deterioration of the preterm neonate, standardized clinical and ultrasound scorin...

Patent ductus arteriosus in the preterm infant.

The ductus arteriosus is a communication between the main pulmonary trunk and the descending aorta. In utero, the ductus arteriosus allows blood flow to be diverted from the high-resistance pulmonary circulation to the descending aorta and the low-resistance placental bed. Functional closure of the ductus arteriosus occurs soon after birth but can be delayed in premature infants and in certain ...

Aortography in infants.

Making a diagnosis of a patency of a ductus arteriosus is often difficult in the first few months or first year of life. When the diagnosis is in doubt, one may profitably turn to angiocardiography for help. In this paper a method of demonstrating the patent ductus by the injection of contrast medium is described. The practical importance of the correct diagnosis is presented with reference to ...

Diagnosis of patent ductus arteriosus in the preterm newborn.

An unusual cause of a continuous murmur simulating persistent ductus arteriosus and associated with other congenital cardiac defects.

A continuous murmur like that of a persistent ductus arteriosus produced by a stenosed branch of a pulmonary artery with a post-stenotic dilatation is presented in the following case. Other abnormalities included a hypoplastic left lung, atrial septal defect, ventricular septal defect, and an absent left pulmonary artery. The literature on congenital heart disease contains increasing numbers of...
