| ASD abbr. atrial septal defect |
ASD,
abbreviation for atrial septal defect.
atrial [a´tre-al]
pertaining to an atrium.
atrial natriuretic factor (ANF) a hormone produced in the cardiac atrium; it inhibits renin secretion and thus the production of angiotensin, and stimulates aldosterone release. Its effect is increased excretion of water and sodium and a lowering of blood pressure, which reduces the workload of the heart.
atrial septal defect a congenital heart defect in which the ostium primum or ostium secundum, openings in the septum primum of the embryonic heart, fail to close completely after birth. When an opening remains between the atria, some of the oxygen-rich blood from the left atrium passes into the right atrium and travels back to the lungs without being first transported through the body. 
Atrial septal defect. The shunt is from left atrium to right atrium. From Betz et al., 1994.

Q. In the future will he with ASD ever be able to live independently? I have a friend who is staying as a paying guest and is being taken care of by all our family members. In the future will he with ASD ever be able to live independently?
A. I am very much moved by your deeds.
• Many people with autism do flourish and go on to hold responsible jobs and live independently. Others have the intellectual abilities to be employed but are held back by their inability to adapt socially to the stresses of everyday life.
• The focus of every intervention program for the person with autism should be to work on helping them adapt to living in society. Their quality of life and ability to function is far more important than how they do on an I.Q. test.
