GONZALEZ-HERNANDEZ, Oscar Rene et al. Abnormal origin of the right pulmonary artery from the aorta. Case report and literature review. Cardiovasc. metab. sci [online]. 2019, vol.30, n.4, pp.150-156.  Epub Aug 12, 2024. ISSN 2954-3835.

A 43 y/o male with a history of patent ductus arteriosus and corrective surgery of the defect performed at 11 years of age. He remained asymptomatic for a long time until he developed shortness of breath on moderate effort, associated with palpitations, productive cough and hemoptysis. On the initial investigation by Internal Medicine, he was diagnosed with a right basal pneumonia, and as part of the diagnostic approach, a chest CT scan was made, which reported an abnormal origin of the right main pulmonary artery from the ascending aorta. He was transferred to the National Institute of Cardiology, where a MRI and a cardiac angiography were performed. The diagnosis was confirmed and pulmonary hypertension was also reported. The case was discussed by the heart team, and it was decided to take him to corrective surgery. The procedure was performed two months later, with the implantation of the right pulmonary branch to the main pulmonary artery using a synthetic Dacron tube. This case is presented, since it is extremely rare to find such a pathology, making the diagnosis in adulthood, with an insidious clinical presentation, which also has an adequate clinical evolution, after surgical repair.

Keywords : Abnormal origin; right pulmonary branch; aorta; corrective surgery.
