During early cardiac morphogenesis, the outflow tract must undergo septation via the development and rotational twisting of the truncoconal (conotruncal) ridges. If these ridges form properly but completely fail to spiral as they partition the truncus arteriosus, which congenital cardiac defect will be present at birth?

 When reviewing the chronological timeline of embryonic cardiac morphogenesis, the vast majority of true structural congenital heart defects (CHDs)—such as transposition of the great arteries, common atrioventricular canals, and ventricular septal defects—are formed during which specific gestational timeframe?
