The Bidirectional Glenn (BDG) procedure, also known as the bidirectional cavopulmonary shunt, is a type of heart surgery often performed on neonates with congenital heart defects, specifically those with single-ventricle physiology. This surgical technique connects the superior vena cava (SVC) to the right pulmonary artery, allowing blood to flow passively into the lungs for oxygenation.
