A patent ductus arteriosus (PDA) is a persistent connection between the aorta and the pulmonary artery resulting in left to right shunting. This connection is supposed to close shortly after birth ...

As a result, the DA is more likely to remain patent and the resulting shunt may have important hemodynamic consequences. [4] Doppler echocardiography has given us a window to evaluate the real ...

Background and aims: Patent ductus arteriosus (PDA) is the most common functional cardiovascular disease of preterm infants. Hemodynamic relevance for organs and circulation can neither be derived ...

Background: Indomethacine treatment for patent ductus arteriosus (PDA), might lead to vasoconstriction of cerebral blood vessels and under-perfusion of the brain. A lower infusion rate might ...
