AB Pathologic  changes  in  the  cardiac  valves  requiring  surgical  correction  of  more  than  one  valve  can  result  from  rheumatic  heart  disease,  degenerative  valve  diseases,  infective  endocarditis,  and  a  number  of  miscellaneous  causes.  Further,  valve  dysfunction  may  be  primary;  that  is,  a  direct  result  of  a  disease  process,  or  secondary;  that  is,  caused  by  cardiac  enlargement  and/or  pulmonary  hypertension.  Surgical  management  is  influenced  both  by  the  underlying  cause  of  valve  dysfunction  and,  when  valves  are  involved  secondarily,  by  the  anticipated  response  to  replacement  or  repair  of  the  primary  valve  lesion.  In  addition,  the  consequences  of  various  combinations  of  diseased  valves  on  left  and  right  ventricular  geometry  and  function  frequently  are  different  from  the  remodeling  as  a  result  of  single-valve  disease.  This  chapter  addresses  pathophysiologic  considerations  in  multivalvular  heart  disease,  surgical  techniques,  and  management  of  commonly  encountered  etiologies.
