Fler medfödda hjärtfel upptäcks med utökad screening i tre steg

SUMMARY
High prenatal detection rates of complex congenital heart defects (CHD)
Aim: To analyze prenatal detection rates of complex CHD after the
implementation of an expanded three-tiered screening model at the
Skane University Hospitals in Lund and Malmö in 2015.
Methods: Retrospective review of pregnancies screened from January
1, 2015 and being born by June 30, 2018. Complex CHD was defined as
needing intervention in the first year of life.
Results: In 27675 screened pregnancies, 51 out of 65 (78 %) cases of
complex CHD were detected prenatally. Exclusion of isolated ventricular
septal defects yielded detection rates of 93 %. All patients needing surgery
within 30 days, potential univentricular hearts and D-transposition of the
great arteries were identified, whilst detection rates for tetralogy of Fallot,
atrioventricular septal defect and coarctation were about 90 %.
Conclusion: Our three-tiered model results in high detection rates of
complex CHD with optimized resource utilization
