Abstract Univentricular atrioventricular connection affects approximately 3 % of infants born with congenital heart disease. Early palliative procedure for such infants is mandatory with the goal to relief cyanosis, prevent damage to ventricular functions and pulmonary vasculature, and facilitate future definitive repair by preserving physiologic parameters. The cavopulmonary shunt (superior vena cava to the right pulmonary artery) provides partial physiological correction for those infants. Its main advantage is to provide obligatory pulmonary blood flow, and avoid left ventricular volume overload accompanying systemic-to-pulmonary artery shunt. (2) There have been numerous studies looking at the timing of the BDG procedure, with many highlighting the potential benefits of performing an ‘‘early’’ BDG procedure. These include removing a volume load from the single ventricle that can benefit atrioventricular (AV) valve insufficiency and perhaps improve longterm diastolic function, decreasing the effective cardiac output required from the single ventricle, avoiding potential pulmonary tree distortions seen with systemic to pulmonary shunts, and perhaps preventing the development |
