Right aortic arch with aberrant left subclavian artery revealed by a dyspnea: A case report

Introduction: Congenital cardiovascular diseases affect about 1% of live births. In 15–20% of cases, this is an anomaly of the aortic arch that includes various malformations with a common embryological origin and which may be asymptomatic or manifest by signs of compression of the tracheoesophageal axis. The diagnosis is sometimes accidental during a radiographic examination, especially in adults. Case Report: We report a clinical case of asymptomatic right aortic arch, discovered during dyspnea. Conclusion: Right-sided aortic arch is a rare anatomical variant present in 0.1% of adult population. It is associated with an aberrant left subclavian artery and half of the cases causing dyspnea or dysphagia. Specific imaging feature can lead to diagnosis and help choose an appropriate treatment.
