title: Delayed recognition of haemodynamically relevant congenital heart disease.
abstract: Delayed recognition of congenital heart defects may have a serious impact on the long-term outcome of the children affected. It was the aim of the present study, to evaluate the proportion of children with delayed cardiac diagnosis out of a large cohort of consecutive paediatric patients requiring treatment for congenital heart disease. A prospective study was performed over a 3-year period. Of all 323 paediatric patients requiring surgical (n = 291) or catheter interventional (n = 32) treatment for congenital heart disease, patients with delayed diagnosis of their cardiac defects were observed and especially examined for the presence of clinical cardiac findings other than systolic murmurs, not recognized as such prior to referral. Of all the patients, 32 (10%) had delayed diagnosis of heart defects. Surprisingly, the proportion of late diagnoses was not different in the group of patients with cyanotic heart disease where 7/72 patients were referred with delay, compared to 25 delayed referrals among 251 children with acyanotic heart defects. Of the 32 patients with delayed diagnosis, 7 had complications due to delayed referral, but there was no mortality associated with late diagnosis.
  
  
  CONCLUSIONS
  A substantial proportion of all paediatric patients requiring intervention for heart disease were diagnosed with relevant delay. In all study patients with late diagnosis, clinical cardiac findings other than systolic murmurs were present that should have alerted the physician on the possible presence of underlying heart disease.
