title: Leaving antegrade pulmonary blood flow results in reversal of flow in the azygous vein and decompression of the cavopulmonary circulation: mechanism of cyanosis defined with cardiac magnetic resonance imaging.
abstract: We report the case of a 2.5-year-old patient with single-ventricle physiology who underwent cardiac magnetic resonance study for cyanosis after Kawashima operation. Magnetic resonance imaging study showed a veno-venous collateral redirecting systemic venous flow, responsible for cyanosis.
