From: Chest CT examinations in patients presenting with acute chest pain: a pictorial review
A 61-year-old female patient visited the ED with chest pain and mild dyspnoea. The patient was diagnosed with atrial fibrillation and had carried a pacemaker since 2000. Echocardiography showed a questionable patent ductus arteriosus (PDA). A thoracic CTA was ordered. Patent ductus arteriosus. (a) CT axial image shows a tubular structure (arrow) abutting aorta with adjacent coarse calcification. (b) Sagital multiplanar reconstruction shows enhanced blood flowing from aorta to pulmonary artery via patent ductus arteriosus
