Sano shunt

Last revised by Deleted User on 02 Aug 2021

The Sano shunt is a palliative surgical technique sometimes used as a step in Norwood procedure for hypoplastic left heart syndrome.

The procedure involves placement of an extracardiac conduit between the right ventricle and main pulmonary artery stump. This technique prevents the reduced diastolic blood flow into the coronary arteries (coronary steal phenomenon) associated with Blalock-Taussig shunt.
