A – Schematic diagram of right ventricle interior, division of the crista supraventricularis into three branches (I, II, III). B – Interior of the right ventricle, division of the crista supraventricularis into three branches; sub-type IIb of the septomarginal trabecula (♂, 51 yrs)

IS – interventricular septum, SC – lower part of the crista supraventricularis, ST (I) – septomarginal trabecula. APM – anterior papillary muscle, SC – lower part of the crista supraventricularis, I in black circle – septomarginal trabecula, II – second branch of the SC, III – third branch of the SC
