Dr. Smita Mishra, Paediatric Cardiologist, Associate Director - Jaypee Hospital, will talk about the treatment of tetralogy of Fallot in this video. If these kids are not very symptomatic in first 5-6 months of age then they are allowed to grow and keep monitoring their saturation level. If saturation is above 70% then they are allowed to grow up to 6-7 kg of weight. If the baby is blue and gets cyanotic spells, an early surgery can be planned.
