The Bi-directional Cavo-pulmonary shunt (BCPS) involves connecting the Superior Vena Cava (SVC) to the right branch of the pulmonary artery and dividing or tying up the pulmonary artery.
This allows venous blood from the head and upper limbs to pass directly to the lungs, bypassing the right ventricle. The venous blood from the lower body however will continue to enter the heart.
This procedure is also known as Bi-directional Cavo-pulmonary Connection (BCPC) or the Bi-directional Glenn shunt. It is sometimes called a "Hemi Fontan" as it is an intermediate stage towards the final Fontan operation.
