Werndale Hospital is a trusted healthcare provider for Norwood Procedure, offering complex neonatal heart surgery supported by experienced pediatric cardiac surgeons, specialized operating facilities, and multidisciplinary intensive care. Established in 1991, the accredited hospital is situated in Carmarthen, United Kingdom and has 19 beds.

The Norwood Procedure is generally the first stage of a staged surgical pathway for infants with single-ventricle physiology, particularly those with hypoplastic left heart syndrome. The operation reconstructs the pathway from the right ventricle to the systemic circulation and establishes controlled blood flow to the lungs. Before surgery, the cardiac team evaluates the baby's heart anatomy, ventricular function, pulmonary blood flow, oxygen levels, and other factors that may affect surgical planning and recovery.
