Atrioventricular septal defect is an opening between all four chambers
of the heart that is present at birth (congenital heart defect). The opening is caused
by a failure of heart tissue to come together during the growth of the
Atrioventricular septal defect results in a large opening in the
center of the heart, with a hole between the 2 lower chambers (ventricular
septal defect) and between the 2 upper chambers (atrial septal defect).
Atrioventricular septal defect requires surgery to correct.
