Heart defects and diseases
What is a Congenital Heart Defect?
Approximately 500 children with congenital heart defect are born each year in Finland. Heart diseases of children are mostly structural defects. It is estimated that approx. 1 % of all infants born each year have a heart defect. Structural heart defects are amongst the most commons anomalies of any singular organ of a human being. Heart defect can also be associated with certain syndromes, such as Down’s Syndrome or Catch-22 Syndrome. However, most children with heart defects do not have any additional structural defects.
Heart of a fetus develops during the first seven weeks of a pregnancy. The development of a heart is extremely complex series of events. If the development is interrupted for some reason, this may result in a structural deformation of a heart. The reasons for the interruption in the developmental period are yet unknown by medical science. It has been suggested that a combination of several factors may contribute to the development of a heart defect – including sheer coincidence. In addition, hereditary factors, some medication or disease, such as German measles suffered during pregnancy may cause heart defects.
As the reasons for the development of a heart defect are unknown in most cases, parents of a child may easily blame themselves for it. Although it is an understandable reaction, it is also totally unnecessary – the doings or non-doings of parents cannot be pointed out as the determinative factors behind the congenital heart defects.
When a Heart Defect Is Detected During Pregnancy
Thanks to advanced diagnostic methods, the number of heart diagnoses detected during pregnancy has increased. It has been found that a prenatal diagnosis improves the prognosis for the unborn child. It allows for, among other things, the pre-planning of procedures and, in some cases, even the initiation of treatment during the fetal stage. It is also beneficial for parents to have time to prepare for the situation and to receive information about the impact of the heart defect on life, both from a medical perspective and through shared experiences.
Fetal Screenings
Municipalities offer pregnant women the opportunity to participate in fetal screenings, such as ultrasound examinations and/or blood screenings.
