Background:
Right ventricular volume overload is the key finding in a patient with previously undiagnosed atrial septal defect (ASD).
Case Summary:
A 68-year-old female was referred to our hospital due to progressive pulmonary artery dilatation observed on her chest X-ray. Echocardiography revealed a secundum ASD with right ventricular dilatation. She had undergone aortic root replacement and aortic valve replacement for annuloaortic ectasia and aortic insufficiency 12 years prior to the diagnosis. She was also diagnosed with Marfan syndrome, which was supported by family histories. Computed tomography did not show a secundum ASD before the surgery. We finally closed the secundum ASD with catheter closure device.
Discussion:
Ascending aneurysm might mask the presence of secundum ASD. Monitoring the change in pulmonary artery dilatation overtime is useful for the diagnosing secundum ASD.
