Interatrial septum, though it sounds like a two-dimensional structure, it is really a three-dimensional structure. Embryologically, this complex septum is contributed by endocardial cushion (A), septum primum (B), septum secundum (C), and septum spurium (D). Septum spurium is formed by RVV and LVV at their dorsocranial end and left venous valve (E); right venous valve (F) which is the forerunner of crista semilunaris, eustachian valve, and thebesian valve; (G) and (H) mark the left and right borders of interseptovalvular space; (I) the flap valve mechanism in FO, which allows only right to left shunt in embryonic period.
