AB Left  ventricular  (LV)  dysfunctions  (systolic  and  diastolic)  are  common  in  the  critically  ill  patient.  They  may  be  due  to  preexistent  disease  (e.g.,  coronary  artery  disease  [CAD])  or  acquired  as  a  part  of  a  clinical  syndrome  responsible  for  the  intensive  care  unit  (ICU)  admission  (e.g.,  septic  cardiomyopathy).  Clinical  examination  alone  or  in  combination  with  chest  radiography  may  be  insufficient  for  assessing  LV  function  in  the  ICU.  Echocardiography  will  provide  crucial  information;  thus,  echocardiographic  assessment  of  LV  function  is  necessary  in  nearly  all  ICU  patients.  Other  technologies,  such  as  bioreatance  (NICOM)  and  thermo  or  marker  dilution  (LiCO,  PICO),  may  provide  additional  information  that  can  also  be  useful.  Indwelling  Doppler  devices  assessing  aortic  blood  flow  have  been  utilized  with  variable  degree  of  success.  Finally,  carotid  artery  blood  flow  measured  ultrasonographically  has  been  recently  suggested  as  an  alternative  to  more  technically  challenging  analysis  of  the  transaortic  stroke  volume  (SV)  (cardiac  output  [CO]).  All  of  these  methods  assist  in  assessing  the  LV.
