[Scimitar syndrome--case report].

: Scimitar syndrome is a rare congenital anomaly. This syndrome is characterized by partial or complete anomalous pulmonary venous drainage of the right lung to the inferior vena cava. There is a characteristic abnormal radiographic shadow which descends along the right cardiac border (scimitar sign). We examined 71-year old woman with severe pulmonary hypertension due to a large shunt between pulmonary veins and right atrium. Other cause of pulmonary hypertension is atrial septum defect. Our patient required permanent pacemaker implantation for tachy-brady syndrome.
