Aim: To assess the usefulness of perioperative transoesophageal echocardiography in evaluating the severity of residual lesions, based on the type of congenital heart disease repaired in paediatric patients.
Methods: A retrospective analysis was conducted on paediatric patients who underwent open-heart surgery at our tertiary centre over a four-year period.
