The video talks about the follow-up of TGA babies by Dr. Smita Mishra, Paediatric Cardiologist, Associate Director - Jaypee Hospital. After surgery, the follow-up period remains the same such as one month, three months, six months and one year. They should also undergo echocardiography to check the growth of the pulmonary artery and the aorta which can be seen properly. There might be a rare possibility of narrowing of the pulmonary artery. These children generally do well and no intervention is needed later in life.
