Werndale Hospital provides specialised TOF Repair with a focus on precise anatomical correction, advanced pediatric cardiac surgery, and individualized postoperative and long-term follow-up care. Established in 1991, the accredited hospital is located in Carmarthen, United Kingdom and operates 19 beds, with modern pediatric cardiac, intensive-care, imaging, and rehabilitation infrastructure.

TOF Repair can restore more effective circulation by correcting the ventricular septal defect and improving blood flow from the right ventricle to the lungs. Treatment planning considers the severity of pulmonary obstruction, ventricular anatomy, pulmonary artery development, coronary artery anatomy, oxygen saturation, and the child's overall health. A detailed preoperative assessment using echocardiography and, when necessary, advanced cardiac imaging helps the pediatric cardiac team select the most appropriate repair strategy and plan postoperative monitoring.
