Embryology and developmental defects of the interatrial septum.
OBJECTIVE
The various types of atrial septal defects (ASDs) can be differentiated on the basis of their imaging appearance on MDCT.


CONCLUSIONS
It is fundamental for the cardiac imager to understand the embryologic development of the interatrial septum and the morphogenic differences of ASDs.
