Atrial Septal Defect - A New Perspective on the Cardiac Dyspnea

The congenital cardiac diseases predominately affect the children, as well as the young adults, and they are the consequence of an abnormal embryological development.

Atrial septal defect (DSA) is a congenital heart malformation, which can close in the first year of life, being shown by the presence of a communication between the left atrium and right atrium with the left-to-right shunt, and it subsequently produces some complications.

We report the case of a 31 years-old-female without previous medical history, who was diagnosed with atrial septal defect.
