Embryological Development of the Apical Trabeculated Region of Both Ventricles. The Contribution of the Primitive Interventricular Septum in the Ventricular Septation
The apical trabeculated region of the anatomical right ventricle has two boundaries, one with its inlet and the other with its outlet, which correspond to the base of the papillary muscles and to the proximal or free border of the supraventricular crest, respectively. The apical trabeculated region of the anatomical left ventricle also has two limits, one with its inlet and the other with its outlet, which are the base of the papillary muscles and a tangential plane at the free border of the free portion of the anteroseptal leaflet of the mitral valve (mitroaortic continuity), respectively (chapter X).
