Introduction

The Fontan procedure is a complex but life-saving heart surgery performed in children born with single ventricle heart defects—conditions where only one ventricle functions effectively. It is typically the third in a series of surgeries that help reroute blood flow, ensuring oxygen-rich and oxygen-poor blood don’t mix, thereby improving oxygenation in the body.

At Innayat Medical, we connect families with India’s leading pediatric cardiac surgeons and top hospitals offering the Fontan procedure. With access to globally accredited heart institutes, advanced surgical technology, and compassionate care, India is one of the most sought-after destinations for pediatric cardiac treatment.

More Information

The Fontan procedure is typically performed on children aged 2–5 years, as the final stage in a three-step surgical approach for conditions such as:

Hypoplastic Left Heart Syndrome (HLHS)

Tricuspid Atresia

Double-Inlet Left Ventricle

Pulmonary Atresia with Intact Ventricular Septum

Procedure Overview:

• Redirects venous blood directly to the pulmonary arteries (bypassing the heart)
• Improves oxygen saturation and reduces cyanosis
• Enhances quality of life and physical activity levels

Types of Fontan Procedures:

• Lateral Tunnel Fontan
• Extracardiac Conduit Fontan Choice depends on patient anatomy and surgeon’s preference.

Recovery involves 1–2 weeks in the ICU and post-op care, followed by regular cardiology follow-up to monitor heart function and prevent complications such as arrhythmias or protein-losing enteropathy.
