Heart Septal Defect | Technology Trends

Heart septal defect refers to a congenital heart defect of one of the septa of the heart.

Atrial septal defect
Atrioventricular septal defect
Ventricular septal defect

Although aortopulmonary septal defects are defects of the aorticopulmonary septum, which is not technically part of the heart, they are sometimes grouped with the heart septal defects.
