AB The  term  “cardiomyopathy”  is  used  to  indicate  myocardial  dysfunction  in  the  absence  of  an  obstructive  lesion  or  sustained  hypertension.  Cardiomyopathy  can  occur  either  in  isolation  or  as  a  manifestation  of  a  multisystem  disease.  Neonates  who  have  an  unrecognized  cardiomyopathy  may  come  to  medical  attention  with  a  life-threatening  decompensation  associated  with  an  otherwise  minor  illness,  such  as  a  viral  upper  respiratory  infection.  Alternatively,  evidence  of  cardiomyopathy  may  be  noted  on  an  echocardiogram  performed  for  evaluation  of  an  unrelated  problem.  Other  conditions  cause  ventricular  dysfunction  but  may  not  have  a  long-term  impact  on  cardiac  muscle  function,  such  as  myocarditis  or  anomalous  origin  of  the  left  coronary  artery  from  the  pulmonary  artery,  and  will  be  discussed  at  the  end  of  the  chapter.
