  1. Patients who underwent closure of a secundum type atrial septal defect are also included in those with atrial septal defect repair. Patients with repair of atrioventricular septal defect include those with the complete and the incomplete type of the defect. The subgroup of subarterial ventricular septal defects is also analysed in the group of ventricular septal defects. Patients with repair of tetralogy of Fallot are also included in the cohort of patients who underwent right ventricular outflow tract surgery.
  2. *including 2 patients with a classic Fontan repair and 29 with total cavopulmonary connections
