AB In  recent  years,  diastolic  function  has  received  greater  recognition  for  its  impact  on  overall  cardiac  performance.  Diastole  is  no  longer  regarded  as  a  passive  phase  of  the  cardiac  cycle,  but  rather  as  a  complex  sequence  of  interrelated  events,  which  are  dependent  on  loading  conditions,  heart  rate,  and  contractility,  and  ultimately  influence  the  systolic  function  of  the  left  ventricle  (LV).  Studies  have  suggested  that  patients  with  diastolic  dysfunction  presenting  for  cardiac  surgery  are  prone  to  hemodynamic  instability  and  potentially  worse  outcomes1  and  that  patients  with  diastolic  heart  failure  are  at  increased  risk  for  decompensation  in  the  perioperative  period.2  Therefore,  the  perioperative  echocardiographer  should  be  familiar  with  the  pathophysiology  of  diastolic  heart  failure  and  understand  how  to  monitor  and  optimize  diastolic  function.  Although  advances  in  ultrasound  technology  have  rendered  Doppler  echocardiography  the  clinician's  “Rosetta  Stone”  for  diastolic  function  evaluation,  this  chapter  will  familiarize  readers  with  all  the  echocardiographic  techniques  routinely  employed  to  assess  LV  diastolic  function,  as  well  as  more  modern  and  sophisticated  methods  of  diastolic  function  assessment,  explain  the  significance  of  these  diastolic  indices,  and  provide  a  diagnostic  algorithm  to  evaluate  perioperative  diastolic  function.
