AB Much  as  the  mitral  valve  (MV)  and  aortic  valve  (AV)  direct  blood  flow  into  the  systemic  circulation,  the  tricuspid  valve  (TV)  and  the  pulmonic  valve  (PV)  direct  flow  into  the  pulmonary  circulation.  The  right  ventricle  (RV)  ensures  loading  of  the  left  ventricle  (LV)  by  pumping  blood  through  the  normally  low  pressure  pulmonary  vasculature.  Perioperative  RV  failure  is  frequently  associated  with  pulmonary  artery  hypertension  and  systemic  hypoperfusion.  Treatment  is  directed  at  reducing  pulmonary  arterial  resistance  to  promote  the  forward  flow  of  blood  into  the  pulmonary  vasculature.  Inotropes  and  ventricular  assist  devices  are  also  used  to  support  right  heart  function  perioperatively.
