At Venkateshwar Hospital, Fontan Procedure is performed using specialized congenital cardiac surgical techniques and comprehensive preoperative cardiovascular assessment. Established in 2016, this NABL, NABH accredited hospital in Delhi, India has 325 beds and offers advanced pediatric and adult congenital cardiac services.

The Fontan Procedure may be considered for patients with complex heart defects such as hypoplastic left heart syndrome, tricuspid atresia, or other conditions resulting in single-ventricle physiology. The surgical team connects the systemic venous circulation directly to the pulmonary arteries, allowing blood to reach the lungs without being pumped there by a ventricle. Detailed assessment may include echocardiography, cardiac catheterisation, CT or MRI imaging, and evaluation of lung and ventricular function before surgery.
