Right anterior views of volume rendered CT angiographies. (a) Right ventricle and (b) left ventricle. (c) The right ventricle is crescent-shaped in cross section. (d) This is a right lateral view showing the three components of the right ventricle and the characteristic muscle bundles as septomarginal trabeculation and supraventricular crest or ventriculoinfundibular fold. Ao = aorta, APM = anterior papillary muscle, AV = aortic valve, CSO = coronary sinus ostium, ICV = inferior cava vein, LAA = left atrial appendage, LV = left ventricle, LVOT = Left ventricle outflow tract, OF = oval fossa, PT = pulmonary trunk, RAA = right atrial appendage, RV = right ventricle, RVOT = right ventricle outflow tract, SC = supraventricular crest, SCV = superior cava vein, SMT = septomarginal trabeculation, and TV = tricuspid valve.
