Embryology and developmental defects of the interatrial septum

AJR Am J Roentgenol. 2010 Nov;195(5):1100-4. doi: 10.2214/AJR.10.4277.


Objective: The various types of atrial septal defects (ASDs) can be differentiated on the basis of their imaging appearance on MDCT.

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