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.
