DESCRIPTION A premature newborn weighing 1.9 kg, presenting with cyanosis, feeding and respiratory difficulties was admitted to our centre for further evaluation. An initial echocardiogram suggested a pulmonary atresia with a malalignment infundibular ventricle septum defect with atypical right-sided ductus arteriosus (2.4 mm) arising from the aberrant right subclavian artery (4 mm), which was ...
Many different anomalies of the coronary vessels have been observed. The minor varieties are quite common, but the more gross forms are relatively rare. An example of one of these gross forms is given in this paper. The variations may be divided into a number of groups: (1) in origin, (2) in number, and (3) in distribution and size. Anomalies in origin are due to the vessel starting abnormally:...
GATA transcription factors play critical roles in restricting cell lineage differentiation during development. Here, we show that conditional inactivation of GATA-6 in VSMCs results in perinatal mortality from a spectrum of cardiovascular defects, including interrupted aortic arch and persistent truncus arteriosus. Inactivation of GATA-6 in neural crest recapitulates these abnormalities, demons...
