Effectiveness of prostaglandin E1 in relieving obstruction in coarctation of the aorta without opening the ductus arteriosus.

The two main theories regarding the pathogenesis of coarctation of the aorta are the Skodaic hypothesis of ductal tissue constricting the aorta at the level of the insertion of the ductus arteriosus and the flow theory of decreased ascending aortic blood flow in the fetus, which results in associated isthmic narrowing and a localized shelf. To document that ectopic ductal tissue constriction can cause coarctation of the aorta in the absence of a patent ductus arteriosus, we report three cases of infants presenting with critical coarctation who responded to prostaglandin E1 infusion without opening the ductus arteriosus.

An isolated left common carotid artery from the main pulmonary artery: possible malseptation of the truncoaortic sac.

An isolated left common carotid artery (LCA) is an extremely rare condition with only four reported cases. In each case, the isolated carotid artery connects to the right or left pulmonary artery via the ductus arteriosus and the embryologic basis for the abnormalities is believed to reflect an error in the development of the branchial arches. We present a case of an isolated LCA connecting to the main pulmonary artery in association with a right aortic arch and an anomalous origin of the left subclavian artery from the descending aorta. The left ligamentus arteriosus was identified separately. This may represent a disturbance in the septation of the truncoaortic sac secondary to abnormal migration of neural crest cells rather than a pure developmental anomaly of the branchial arches.

Secundum-type atrial septal defects with failure to thrive in the first year of life.

This article summarizes the case histories of six infants who had isolated secundum-type atrial septal defects (ASDs) and presented with failure to thrive in the first year of life. Patients underwent operative closure of their ASD with the expectation that this would improve their feeding and growth pattern. Five of the six children demonstrated little or no improvement in symptoms following operation. Each of these five patients have subsequently shown signs of developmental delay. Our experience with this group suggests that failure to thrive associated with a secundum ASD will frequently have a noncardiac basis.
