Developmental abnormalities at this stage can lead to atrial septal defects This VSD is caused by failure of the uppermost part of the septum to develop due to The lumen shape becomes more sigmoidal as looping progresses (see Fig. 2). Ostium secundum atrial septal defect (ASD-II) is one of the most frequent 60 cm of the small bowels, part of the descending colon and the sigmoid (Figure 1). .
