A Sano shunt is a shunt from the right ventricle to the pulmonary circulation.[1][2][3]

In contrast to a Blalock–Taussig shunt, circulation is primarily in systole.[citation needed]

It is sometimes used as the first step in a Norwood procedure.[citation needed]

This procedure was pioneered by the Japanese Cardiothoracic Surgeon, Shunji Sano (b.1953) in 2003.[4]
