Figure 2: (a) Cardiac magnetic resonance steady-state free precession still frames. The images clearly show that the interatrial groove (the embryonic septum secundum) is made up by the folding of right and left atrial walls. (b) Anatomic specimen displayed in similar view. (c) In a more posterior cut, the fossa ovalis disappears and this enfolding assumes a “three layered” aspect (see text). (d) Magnified image of the red box of panel c
