Prenatal screening for foetal cardiac abnormalities has been increasingly practiced in Sweden during the last 25 years. A prenatal diagnosis may have medical benefits but may also cause sustained parental psychological distress. The aim of this study was to explore pregnant women’s, and their partner’s, experiences of counselling and need for support during continued pregnancy following a prenatal diagnosis of a cardiac defect. A second aim was to use this information to propose a structured follow-up programme for continued support after the first counselling. Design: Qualitative study, using interviews performed 5–9 weeks after a prenatal diagnosis of congenital heart disease. Setting: A tertiary foetal cardiology unit in Sweden Sample: Six pregnant women and their 6 partners, consecutively recruited after a prenatal diagnosis of an isolated and significant cardiac defect. Data analysis: Qualitative content analysis. The analysis resulted in three themes. 1/ Counselling and making a decision - the importance of knowledge and understanding: Short waiting time for specialist evaluation together with clear and straightforward information was essential. Parents called for written information together with a high-quality website with relevant information about congenital heart disease. 2/ Continued support during pregnancy: Continued and easy access to health care professionals, including a paediatric specialist nurse, throughout pregnancy, was important. Contact with couples with similar experiences and social media were also considered valuable sources of support. 3/ Next step – the near future: Practical and economical issues during the postnatal hospital stay and the initial period following the hospital stay were common concerns. The following aspects should be considered in a structured follow up program during pregnancy after a prenatal diagnosis of CHD; written information, access to a safe web-site with information of high quality in their native language, support from parents with similar experiences and continued contact with a specialist liaison nurse with experience of paediatric cardiology.

To determine what proportion of newborns with critical heart defects are discharged undiagnosed from the maternity ward. Data were retrieved retrospectively for infants born in our referral area from 1993 to 2001 and undergoing surgical or catheter-based intervention before 2 mo of age because of critical heart defects. 259 full-term infants had critical heart defects. Duct-dependent systemic circulation was present in 129, duct-dependent pulmonary circulation in 106, and 24 infants were not duct dependent but critically ill. In 51 infants (20%) the heart defect was not suspected before discharge from the maternity ward. Such late detection occurred more often in infants with duct-dependent systemic circulation (30%) and in children with defects that were not duct dependent (38%) than in children with duct-dependent pulmonary circulation (4%) (p<0.001). The proportion detected after discharge from the maternity ward increased from 13% in 1993-1995 and 21% in 1996-1998 to 26% in 1999-2001 (p<0.05). Many infants with critical congenital heart defects are not diagnosed before discharge from the neonatal maternity ward. The proportion discharged undiagnosed has increased. Neonatal screening fails mainly in children with duct-dependent systemic circulation.

OBJECTIVES: To determine what contribution prenatal ultrasound screening and neonatal pulse oximetry screening (POS) make to the timely diagnosis of neonatal coarctation of the aorta (CoA). METHODS: We identified infants and fetuses diagnosed with isolated CoA in our referral area between 2003 and 2012 who died without surgery, underwent surgical repair before 2 months of age, or were terminated after a prenatal diagnosis. Clinical data were collected from hospital charts. RESULTS: Only 3 of the 90 cases were diagnosed prenatally. Two of the 3 were born alive and in 1 case the couple opted for termination of pregnancy. Nineteen of the remaining 87 cases were born in units that used POS (hand and foot) and 4 of 19 screened positive. Of the remaining 83 cases, 46 were discharged undiagnosed (7 after nondiagnostic echocardiography), including 9 with a murmur and weak femoral pulses and 8 with a murmur and normal pulses. One was diagnosed postmortem after dying at home, and 22 of the remaining 45 discharged infants were in circulatory failure on readmission. Five of the patients who were not discharged died without surgery and undiagnosed CoA was the most probable cause of death in 2 of these patients. CONCLUSIONS: The contribution of prenatal ultrasound screening and postnatal POS to the timely diagnosis of CoA was low. Careful physical examination of all newborns therefore continues to play a fundamental role in detecting this life-threatening cardiac defect, and better screening methods need to be developed.

Approximately 1-2 per 1000 newborn babies have a cardiac defect that is potentially life-threatening usually because either the systemic or the pulmonary blood flow is dependent on a patent ductus arteriosus. A significant proportion of newborns with such cardiac defects are being discharged from well-baby nurseries without a diagnosis and therefore risk circulatory collapse and death. This risk is greatest for defects with duct-dependent systemic circulation, notably aortic arch obstruction, but is also significant in transposition of the great arteries, for example. The solution to this problem, apart from improving prenatal detection rates, is to introduce effective neonatal screening including routine pulse oximetry.
