Truncus arteriosus communis is a congenital heart malformation, which is usually repaired in the neonatal period or early infancy. Although results of repair are good, there is long-term morbidity caused by reoperations mainly owing to right ventricle to pulmonary artery conduit exchange or stenosis at the pulmonary artery bifurcation as recently reported for Contegra conduits. We present a new...

It was found that the ductus arteriosus is a muscular channel and resembles the muscular artery in structure. The diameter of the ductus is equal throughout its length. At the orifice of the ductus to the aorta the cells of its wall blend with those of the aorta. The primordia of the tunica media of the aorta and the pulmonary trunk consist of regularly arranged, circular layers which are more ...

The combination of patent (luctus arteriosus land coarctation of the aorta poses special anatomic, physiologic and surgical proldems. An experience with 14 such cases is presented, wVhich suggests that pulmonary hypertension occurs frequently in these cases. Physiologic data in cases having coarctation of the aorta, patent (luctus arteriosus and pulmonary hypertension that underwent cardiac cat...

Here, we report a fetus with a rare aortic arch anomaly with left aortic arch and right ductus arteriosus, which has not been reported so far. In this condition, the aorta extends to the left of the trachea as in normal, while the ductus arteriosus extends to the right of the trachea and joins the descending aorta posterior to the trachea, with a cross-ribbon sign.

OBJECTIVES: Ibuprofen is a non-selective anti-inflammatory cyclooxygenase inhibitor drug of the propionic acid class of non-steroidal agents, available without prescription in the USA. In preterm infants, ibuprofen is used to close the Patent Ductus Arteriosus and it was found to be more effective than indomethacin. This metaanalysis determined whether differences exist in the closure rate of P...

Heart failure and persistent respiratory insufficiency associated with patent ductus arterioeus occur frequently in lowbirth-weight infants.'-" Surgical ligation of the patent ductus arteriosus (PDA) has been advocated when conservative medical management fails.3 '7 This report describes our experience with 14 patients averaging a weight of less than 1500 grams each who were presented for thora...
