Traditionally the pulmonary circulation has been supplied via a modified Blalock Taussig (BT) shunt but a recent modification, adopted in some UK centres, substitutes a conduit between right ventricle and pulmonary arteries (RV-PA conduit). It is argued that this will result in a more favourable balance between pulmonary and systemic circulations.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Aim:<\/jats:bold> To compare the early postoperative haemodynamic profile between patients undergoing a BT shunt or an RV-PA conduit.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Methods:<\/jats:bold> Retrospective review in a tertiary referral PICU of 51 children with HLHS undergoing the Norwood procedure with either a BT shunt (Group 1; n\u200a=\u200a23) or an RV-PA conduit (Group 2; n\u200a=\u200a28).

No between-group differences were found in markers of pulmonary blood flow (PaO<jats:sub>2<\/jats:sub>, PaCO<jats:sub>2<\/jats:sub>, PaO<jats:sub>2<\/jats:sub>\/FiO<jats:sub>2<\/jats:sub> ratio), or in markers of systemic blood flow (blood lactate, oxygen extraction ratio), or in estimated ratio of pulmonary:systemic blood flow (Qp:Qs).
