Why is the Bidirectional Glenn Procedure Necessary?
In neonates with single-ventricle physiology, the heart cannot effectively pump blood to both the lungs and the body. The BDG procedure helps to separate the pulmonary and systemic circulations, reducing the workload on the single functioning ventricle. This staged approach improves oxygenation and prepares the child for the final stage of surgical correction, often a Fontan procedure.
