The newborn can survive for a few days while the foramen ovale, a small hole in the septum that separates the two atria, is open, allowing some oxygenated blood to escape and mix into the blood that is being pumped throughout the body.
A procedure called a cardiac catheterization can then be performed during which a small thin tube (catheter) with a balloon tip, may be used to enlarge the opening between the two atria until surgery can be performed.
The most common types of septal defects are atrial septal defect, an opening between the two upper heart chambers (atria), and ventricular septal defect, an opening between the two lower heart chambers (ventricles).

The town occupies the site of the ancient Atria, which gave its name to the Adriatic. Its origin is variously ascribed by ancient writers, but it was probably a Venetian, i.e.

The atria are comparatively small, the walls being thin, especially those of the right, which possesses numerous muscular ridges projecting into the cavity presenting a honeycombed appearance.
