Typical signs of secundum atrial septal defect in a young female.

We report the case of a 25-year-female presented with dyspnea & chest pain on exertion. The ECG showed signs of right ventricular overload. The chest X-ray showed an enlargement of central pulmonary arteries, pulmonary plethora and a small aortic knuckle. Atrial septal defect (ASD) was suspected and transthoracic echocardiography (TTE) subsequently confirmed the presence of a large ostium secundum ASD. A surgical closure with an equine pericardium patch was performed. Two months after the surgical repair, the ECG and TTE showed the regression of signs of right ventricular overload.
