Figure 2. Enlarged cardiac silhouette with prominent pulmonary trunk and pulmonary arteries proximally.
A chest CT was done to find out what was causing the high blood pressure in the pulmonary arteries. The scan showed volume loss in the right hemithorax. The CT scan also showed a patent ductus arteriosus and an abnormal origin of the right pulmonary artery from the right ascending aorta, which has compressed the right main bronchus Figure 3. A spirometry analysis was avoided due to ongoing hemoptysis and infection.
