The 2009/12 paediatric cardiac surgical procedures are defined as any cardiac or intrathoracic great vessel procedure carried out in patients under the age of 16 years. This all centre aggregated analysis was conducted using PRAiS software (version 2.2). PRAiS estimates the risk of death within 30 days of a primary surgical procedure, based on specific procedure, age, weight and the patient recorded diagnoses and comorbidities. The PRAiS model can only be applied to paediatric cardiac surgery and has not been validated for use in an adult congenital population. To date, there are no risk adjustment models available for these patients. Therefore similar overall aggregate figures for adults with congenital heart disease are not possible. The figure below shows the number of surgical episodes, 30 day survival rates and predicted and actual survival ratios
Please note that this is a reanalysis of data that was originally published in April 2013.
