Not in isolation: Coarctation only causes cyanosis when it is associated with other heart disease that allows blue blood to cross over to the red blood side. Cyanosis occurs in two situations: 1. When blue blood gets to the red blood side ("right-to-left shunting) or 2. When blood is not fully oxygenated in the lungs ("pulmonary venous desaturation").
