AB  - In  U.S.  patients  over  the  age  of  65  years,  the  prevalence  of  moderate  or  severe  aortic  stenosis  (AS)  or  aortic  regurgitation  is  4.1%  and  3.0%,  respectively.1  Surgical  aortic  valve  replacement  (SAVR)  is  the  most  common  valve  replacement  procedure  and  the  second  most  common  cardiac  operation  following  coronary  artery  bypass  grafting  (CABG)  in  the  United  States.  Demographic  studies  estimate  the  current  potential  population  of  patients  suffering  from  severe  AS  needing  an  aortic  valve  replacement  (AVR)  is  estimated  at  350,000  and  is  forecasted  to  increase  with  our  aging  population.2  Recent  studies  indicate  that  between  33%  and  69%  of  patients  with  symptomatic  aortic  stenosis  who  may  be  potential  candidates  for  valve  procedures  never  undergo  an  intervention,  suggesting  that  improved  compliance  with  guidelines  or  expanded  applications  of  technologies  should  increase  valve  procedures.1,3,4  Utilization  of  transcatheter  aortic  valve  replacement  (TAVR)  continues  to  increase  and  redefine  the  management  of  aortic  valve  disease  in  patients  of  various  surgical  risk.2,5  Analysis  of  clinical  practices  in  New  York  State  demonstrated  a  27%  increase  in  surgical  and  transcatheter  aortic  valve  replacements  between  2011  and  2012,  with  a  146%  increase  in  transcatheter  approaches.6  Intraoperative  transesophageal  echocardiography  (TEE)  alters  the  surgical  plan  in  13%  of  patients  undergoing  aortic  valve  surgery.7  Furthermore,  consensus  statements  from  cardiology  and  thoracic  surgery  societies  have  given  intraoperative  TEE  a  class  I  designation  (“evidence  and/or  general  agreement  that  a  given  procedure  or  treatment  is  beneficial,  useful  and  effective”)  in  patients  undergoing  surgical  repair  or  replacement  of  valvular  lesions.2,8  Thus,  a  comprehensive  TEE  evaluation  of  the  aortic  valve  should  be  performed  in  all  patients,  particularly  those  undergoing  aortic  valve  procedures.
