AB The  right  and  left  coronary  arteries  are  responsible  for  the  delivery  of  oxygenated  blood  to  the  myocardium.  The  right  coronary  artery  is  responsible  for  supplying  oxygen  to  the  right  atrium,  the  right  ventricle,  and  the  inferior  portion  of  the  left  ventricle,  sinoatrial  and  atrioventricular  nodes.  The  distribution  of  the  left  coronary  artery  (LCA)  includes  the  left  atrium,  the  interventricular  septum,  and  the  anterolateral  walls  of  the  left  ventricle.  Branches  of  the  LCA  include  the  circumflex  artery,  which  supplies  the  lateral  wall  of  the  left  ventricle,  and  the  left  anterior  descending  artery  (LAD),  which  supplies  the  anterior  wall  of  the  left  ventricle  as  well  as  the  interventricular  septum.  To  supply  the  myocardium  with  oxygen,  the  blood  flows  from  the  epicardial  vessels  to  the  endocardial  vessels,  and  then  returns  to  the  right  atrium  via  the  coronary  sinus.
