Werndale Hospital provides specialised TAPVC with a focus on precise anatomical reconstruction, advanced neonatal cardiac techniques, and individualised postoperative care. Established in 1991, the accredited hospital is located in Carmarthen, United Kingdom and operates 19 beds, with modern pediatric cardiac surgical and critical-care infrastructure.

TAPVC treatment restores normal pulmonary venous blood flow by connecting the pulmonary veins to the left atrium and correcting associated abnormal pathways. The surgical approach may vary depending on whether the TAPVC is supracardiac, cardiac, infracardiac, or mixed, and whether pulmonary venous obstruction is present. A detailed assessment before treatment helps the cardiac team understand the pulmonary venous anatomy, determine the urgency of repair, and plan the most appropriate surgical strategy.
