Atrial septation. This cartoon depicts the developmental events responsible for the formation of the atrial septal complex (see text). The yellow box in the back of the heart represents the posterior Second Heart Field giving rise to the DMP which in turn develops into the base of the atrial septal complexand becomes muscularized to form the muscular rim (B–D). The asterisk in (A) marks the primary foramen (also known as ostium primum); the asterisk in (C) marks the secondary interatrial foramen (also known as ostium secundum), which forms as a result of perforations in the upper part of the primary atrial septum (see (B)). DMP = dorsal mesenchymal protrusion, pf = primary foramen, FO = foramen ovale, LA = left atrium, LV = left ventricle, PAS = primary atrial septum, RA = right atrium, RV = right ventricle, “rim” = myocardial rim, sAS = secondary atrial septum.
