Centro Medico Teknon provides specialized Fontan Procedure with a focus on precise surgical reconstruction, advanced congenital cardiac techniques, and individualized postoperative care. Established in 1994, the JCI accredited hospital is located in Barcelona, Spain and operates 211 beds, with modern pediatric cardiac surgical and critical-care infrastructure.

The Fontan Procedure can establish a circulation in which systemic venous blood flows directly to the lungs without being pumped by a ventricle. By reducing the volume load on the functional ventricle, the procedure can improve oxygenation and support circulation in appropriately selected patients with single-ventricle physiology. A detailed assessment before surgery helps the cardiac team determine the patient's readiness for Fontan completion and plan the most suitable surgical technique.
