AB Cardiac  tumors  can  be  broadly  classified  into  those  that  arise  primarily  in  the  heart  and  those  that  reflect  metastatic  disease  from  a  distant  primary  source.  Primary  cardiac  tumors  can  be  further  divided  into  those  that  are  pathologically  benign  and  those  that  are  malignant.  Overall,  primary  cardiac  tumors  are  relatively  uncommon,  whereas  secondary  involvement  of  the  heart  or  pericardium  occurs  in  as  many  as  20%  of  patients  with  end-stage  metastatic  cancer.  While  patients  with  cardiac  tumors  may  present  with  a  variety  of  symptoms,  many  patients  are  asymptomatic  at  the  time  of  diagnosis  as  the  tumor  may  be  identified  incidentally  on  imaging  studies  performed  for  other  reasons.  Such  findings  need  to  be  differentiated  from  other  cardiac  masses  such  as  vegetation,  thrombus,  or  myocardial  hypertrophy.  Echocardiography  is  usually  the  initial  method  of  evaluation  of  cardiac  tumors;  however,  a  variety  of  imaging  modalities  are  now  available  and  a  multimodality  approach  is  often  necessary  for  accurate  diagnosis  and  clarification  of  treatment  options  (Table  266-1).
