Atrioventricular canals are congenital abnormalities of the heart that are associated with Down syndrome. Diagnosing atrioventricular canal congenital heart disease helps children detect the disease early and treat it.

Emergency chest X-ray at bedside is a technique indicated in emergency cases requiring X-rays in seriously ill patients who are unable to move or who will make the disease worse, even leading to death. This is a common, minimally invasive technique that is very valuable in diagnosing diseases of the heart, lungs, rib cage, spine, etc. through X-ray images.
