Adults with congenital heart disease, especially the ones who require constant medical care, encounter many psychosocial difficulties. These difficulties also occur in the interventional departments of cardiology and cardiac surgery, where they often have to make important decisions, undergo cardiology interventions and cardiac surgeries, and more rarely they also have to deal with unexpected complications that can lengthen their hospitalisation duration considerably. The literature has also outline predictive factors when it comes to the psychological difficulties encountered in this population. For these reasons, the inclusion of the psychologist in this context is essential.
