. Recognition of the absence of this murmur can indicate a potentially terminal cardiac defect in the newborn.

In the fetal heart, the foramen ovale , also ostium secundum of Born or falx septi, allows blood to enter the left atrium from the right atrium. It is one of two fetal cardiac shunts, the other being the ductus arteriosus...
