Analytical approach and model structure illustrating alternative events and their sequelae. The primary outcome of this analysis is difference in costs between the Baseline scenario and four hypothetical scenarios of improved treatment effectiveness and patient safety. All scenarios include the same events at initial intervention, short-term, and mid-term follow-up. Scenarios differ in the probabilities attached to events. The figure shows possible events in the first period of the model (during or immediately after the initial intervention), and at short- and mid-term follow-up. The same events are included for short- and mid-term follow-up. Hypertension medication and imaging are not dependent on any other events and are therefore not connected to the other events. Hypertension is not directly influenced by other events at follow-up and does not impact on complications or reintervention rates itself. Imaging is recommended for all patients after CoA repair at least every two years [10]. Full circles indicate event probabilities subject to change in scenarios. Dotted circles indicate exogenous event probabilities
