Quantification of left-to-right shunt through Patent Ductus Arteriosus by colour Doppler
… to quantify the size of a shunt through a patent ductus arteriosus (PDA) by ultrasound and to test its usability in clinical settings. There is no consensus regarding the optimal management strategy for a PDA in premature infants. Non-steroidal anti-inflammatory drugs (NSAID) are the first …

The Role of Mitochondria in Oxygen Sensing of the Ductus Arteriosus and Fetal Pulmonary Arteries
… underlie the oxygen responses of the ductus arteriosus (DA), adult pulmonary arteries (PA) and other oxygen sensing tissues. However, the fetal PA oxygen response has been little studied, the identity of the DA oxygen sensor remains elusive, and the basis for the opposing oxygen …

The nature, extent, and range of evidence of the premature constriction or closure of the ductus arteriosus in utero unrelated to known non-steroidal-anti-inflammatory drug exposure: a scoping review
Background: During pregnancy, the ductus arteriosus allows blood to bypass the fetal lungs. Non-steroidal anti-inflammatory drug (NSAID) use in late pregnancy can cause premature constriction or closure of the ductus arteriosus (PCDA), though cases also occur without NSAID exposure. Understanding …

Digital simulation of the neonate cardiovascular and pulmonary systems
… on respiratory stimulus, cardiac output and Ductus Arteriosus shunting. Pulmonary and cardiac system dynamics were not considered in the simulation. The model underwent a series of tests in which controlled mockups of actual physiological conditions were simulated. The effect of metabolic …

Transcriptional Regulation of Neural Crest-Derived Pharyngeal Arch Artery Development
… of the neural crest-derived fetal vessel, the ductus arteriosus, which bridges the pulmonary and systemic circulations during gestation and must close at birth for extrauterine survival. The ductus arteriosus is composed of highly differentiated, contractile smooth muscle. I found that Et-1 is …

Disease burden of Congenital Rubella Syndrome at four referral hospital in Zambia
… cataracts, congenital heart disease (patent ductus arteriosus) and microcephaly. The commonest combined clinical features were congenital heart disease, congenital cataracts and microcephaly (14% {5/36}). Incidence was calculated for 2014 only as it had complete data. The incidence of CRS per …

THE USE OF ENTERAL STERILE WATER FOR THE TREATMENTOF HYPERNATREMIAIN EXTREMELY LOW BIRTH WEIGHT INFANTS
… is associated with comorbidities such as patent ductus arteriosus, bronchopulmonary dysplasia and intraventricular hemorrhage. The purpose of this prospective, randomized control trial (N=19) was to examine the use of enteral sterile water feeds as an alternative management strategy on the …

Cierre percutáneo del conducto arterioso persistente en pacientes pediátricos con hipertensión pulmonar en un centro cardiovascular en Bogotá entre 2019-2022: resultados a corto plazo
Antecedentes: El tratamiento del DAP de gran tamaño en el contexto de hipertensión pulmonar (HP) es un reto. Si se deja permeable, el DAP grande puede provocar una enfermedad vascular pulmonar irreversible. Si se ocluye, puede generar una insuficiencia ventricular derecha. Objetivo: Describir los …

The role of prostaglandins, nitric oxide and oxygen in the ductus arteriosi of the pre-term chicken embryo (Gallus domesticus).
The chicken ductus arteriosi (DA) are two embryonic blood vessels that shunt blood away from the non-ventilated lungs and towards the body and chorioallantoic membrane. I show that prostaglandins have a diminished role in maintaining chicken DA patency and nitric oxide inhibits oxygen induced …
