The<unk>  is a palliative surgical procedure for cyanotic heart defects. This procedure is used to deviate blood flow to the lungs from systemic circulation to relieve cyanosis while a definitive corrective surgery can be performed at a later time. A connection is usually made between the subclavian artery and pulmonary artery. Usually, two types of<unk> s are used: classic or original<unk>  and modified<unk> . The classic/original<unk><unk>  has been modified into modified<unk>  (mBTS). In this modified procedure, a graft from an innominate artery or subclavian artery is placed to the corresponding pulmonary artery. This type of<unk><unk>  has superior prognostic value over the classical<unk>  leading to a greater rate of<unk>  patency in 3-5 years as compared to the classic or original<unk><unk> .
