Structural abnormalities in the heart and blood vessels present at the time of birth are termed as congenital heart disorders. These disorders affect the blood flow in the heart and larges vessels. Congenital heart disorders are one of the major causes of death in infants and children.Congenital heart defect (CHD) or congenital heart anomaly is a defect in the structure of the heart and great vessels that is present at birth. Open access to the scientific literature means the removal of barriers (including price barriers) from accessing scholarly work. There are two parallel roads towards open access: Open Access articles and self-archiving. Open Access articles are immediately, freely available on their Web site, a model mostly funded by charges paid by the author (usually through a research grant). The alternative for a researcher is self-archiving (i.e., to publish in a traditional journal, where only subscribers have immediate access, but to make the article available on their personal and/or institutional Web sites (including so-called repositories or archives)), which is a practice allowed by many scholarly journals.
Open Access raises practical and policy questions for scholars, publishers, funders, and policymakers alike, including what the return on investment is when paying an article processing fee to publish in an Open Access articles, or whether investments into institutional repositories should be made and whether self-archiving should be made mandatory, as contemplated by some funders.
