AB Coronary  angiography  remains  the  gold  standard  for  imaging  coronary  anatomy  and  defining  the  extent  and  precise  location  of  coronary  artery  disease.  Optimal  coronary  angiography  is  dependent  on  a  thorough  knowledge  of  coronary  anatomy  and  a  systematic  imaging  sequence  protocol  that  enables  visualization  of  all  coronary  segments,  particularly  areas  of  vessel  overlap,  bifurcations,  or  tortuous  anatomy.  A  basic  map  of  the  coronary  anatomy  is  delineated  in  Figure  69-1,  and  the  optimal  views  for  imaging  each  coronary  segment  are  summarized  in  Table  69-1  (Figs.  69-2,  69-3,  69-4,  69-5).  Although  standard  views  are  generally  consistent  from  one  patient  to  the  next,  the  precise  angulations  tend  to  vary  based  on  the  variations  in  anatomic  orientations.  A  number  of  coronary  segment  numbering  systems  have  been  established;  the  most  commonly  used  is  the  Coronary  Artery  Surgery  Study  (CASS)  numbering  system  derived  from  the  Bypass  Angioplasty  Revascularization  Investigation  (BARI)  study,1  which  assigns  a  unique  number  to  each  coronary  vessel  segment  and  its  branch  vessels  and  has  gained  wide  acceptance  in  interventional  clinical  trials  (Table  69-2).
