Embryology

  • At about week 4 of pregnancy, the septum primum and septum secundum forms to divide the primordial single atrium into right and left.
  • The crescent-shaped septum primum grows from primordial atrial roof towards the endocardial cushion. This partially divides the common atrium into left and right halves.
