Systemic right ventricle means a right ventricle to which aorta is connected instead of pulmonary artery. Since the right ventricle is not morphologically meant to face the higher load from systemic resistance, it is likely to develop dysfunction in the long run if placed in the systemic position. It may be noted that the geometry of the right ventricle is quite different from that of the left ventricle. Its inlet is guarded by a tricuspid valve instead of a bicuspid mitral valve. The number of papillary muscles are also different in the right ventricle, though it is not always a fixed number of three, whereas the left ventricle has a relatively fixed number of two papillary muscles.
