Atrioventricular Septal Defect, AVSD

In complete AVSD (Atrioventricular Septal Defect), a three-dimensional part of the heart is missing. The lower part of the atrial septum and the upper part of the ventricular septum are absent, and instead of having two separate atrioventricular valves (the mitral and tricuspid valves), there is only one common atrioventricular valve between the atria and […]

Patent ductus arteriosus, PDA

The ductus arteriosus (Botalli) is a vital blood vessel connection between the pulmonary artery and the aorta during fetal development. After birth, it becomes unnecessary and should close on its own within the first few days of life. If the ductus arteriosus does not close normally, oxygen-rich blood flows from the aorta into the pulmonary […]

Atrial Septal Defect, ASD

In this condition, there is an extra opening in the atrial septum (Atrial Septal Defect, ASD). Typically, the fetal oval opening closes during the first year of life, but it can also remain open. In such cases, oxygen-rich blood from the left atrium flows through the atrial septal defect into the right atrium and then […]

Internationality

International cooperation Nordic and European cooperation takes the form of sharing knowledge, experience and approaches to the treatment and development of congenital heart defects, as well as rehabilitation, information and peer-to-peer activities. This cooperation includes organising or participating in meetings and conferences organised by various partners. Heart Children and Adults Association is actively involved in […]

Fetal Circulation

During pregnancy, oxygen and nutrients are transferred to the fetal circulation from the mother’s blood through the placenta. Oxygen-rich, bright red blood flows from the placenta through the umbilical vein to the fetal inferior vena cava. The blood continues to the right atrium, where the Eustachian valve directs the oxygen-rich blood through the oval window […]
