Global Health City provides specialized Glenn procedure with a focus on surgical precision, patient safety, and comprehensive pediatric cardiac care. Established in 1999, the NABH, NABL hospital is located in Chennai, India, and operates 200 beds, equipped with modern healthcare infrastructure.

The Glenn Procedure, also known as a bidirectional Glenn shunt, is used in selected children with complex congenital heart defects and single-ventricle physiology. The procedure connects the superior vena cava to the pulmonary arteries, allowing venous blood from the upper body to flow directly into the lungs. Comprehensive cardiac assessment is performed before surgery to evaluate suitability and plan treatment. After the procedure, intensive monitoring and long-term cardiology follow-up help manage the child's recovery and ongoing heart care.
