Complementary echo and CCTA findings with superior sinus venosus atrial septal defect

Area of Science:

• Cardiology
• Medical Imaging
• Thoracic Surgery

Background:

• Congenital heart defects can manifest in adulthood with progressive symptoms.
• Pulmonary hypertension is a serious condition often linked to underlying cardiac or pulmonary disease.

Observation:

• A young female presented with dyspnea on exertion, indicating potential cardiopulmonary compromise.
• Initial echocardiography revealed right heart enlargement and severe pulmonary hypertension.

Findings:

• Cardiac computed tomographic angiography (CCTA) identified a superior sinus venosus atrial septal defect.
• Anomalous right upper pulmonary venous drainage into the right atrium was confirmed.
• Echocardiography and CCTA provided complementary diagnostic information.

Implications:

• Accurate diagnosis of complex congenital heart disease is crucial for effective management.
• Multimodality imaging, including echocardiography and CCTA, enhances diagnostic precision.
• Early identification and treatment of such defects can prevent severe complications like pulmonary hypertension.
