Choosing Werndale Hospital for Fontan Procedure gives patients access to experienced congenital cardiac surgeons, advanced cardiovascular imaging, pediatric intensive care facilities, and structured postoperative management. Established in 1991, the accredited hospital in Carmarthen, United Kingdom has 19 beds and provides specialised congenital and cardiothoracic surgical services.

The Fontan Procedure is performed under general anaesthesia and involves rerouting venous blood directly to the pulmonary arteries. Different surgical approaches may be used depending on the patient's anatomy, including an extracardiac conduit or lateral tunnel technique. After surgery, patients are closely monitored for circulation, oxygenation, heart rhythm, fluid balance, and other potential complications. Long-term follow-up is important because Fontan circulation requires ongoing cardiac assessment throughout life.
