AB As  the  diagnostic  role  of  cardiac  catheterization  has  diminished  over  the  years,  its  role  as  a  mode  of  primary  therapy  has  exponentially  increased.  In  most  large  congenital  cardiac  centers  today  more  than  70%  of  all  children  undergoing  cardiac  catheterization  have  an  interventional  therapy  as  part  of  the  procedure.  Interventional  cardiac  catheterization  has  become  the  standard  of  care  for  treating  an  increasing  number  of  congenital  heart  lesions,  while  in  others  it  remains  investigational  (Table  499-1).  Common  interventional  procedures  include  balloon  septostomy  in  neonates  with  d-transposition  of  the  great  arteries,  balloon  valvoplasty  in  valvar  pulmonic  or  aortic  stenosis,  balloon  angioplasty  with  or  without  stent  repair  of  branch  pulmonary  artery  stenosis  or  coarctation  of  the  aorta,  device  closure  of  a  patent  ductus  arteriosus,  atrial  septal  defect,  muscular  ventricular  septal  defect,  and  embolization  of  abnormal  venous  or  arterial  vessels.  Investigational  interventional  catheter  based  treatments  include  stented  valve  implant  for  pulmonary  insufficiency,  ductal  stenting  for  first  stage  treatment  of  infants  with  hypoplastic  left  heart  syndrome  or  pulmonary  atresia,  and  fetal  intervention  for  critical  aortic  or  pulmonic  stenosis  to  promote  ventricular  growth  in  utero.
