Scimitar syndrome or Felsons veno-lobar syndrome is a very rare congenital disease characterized by a combination of cardiopulmonary abnormalities, including partial right-sided pulmonary venous drainage to the inferior vena cava, the inferior cavo-atrial junction, or low on the right atrium. We report the case of a 53-year-old female patient who presented with recent gradually worsening dyspnea. The diagnosis was suspected on the chest x-ray and confirmed on Cardiac echography andComputed Tomography scan that showed a wide collector gathering the three right superior pulmonary veins that joins the lower part of the superior vena cava, thus joining the right atrium while the right inferior pulmonary vein is drained into the inferior vena cava. The patient was treated surgically by performing a derivation of the right superior pulmonary venous collector to the left atrium with a tricuspid annuloplasty with a good outcome.
