Kawasaki disease (KD) is an acute febrile illness that can result in life threatening coronary artery aneurysms in up to 25% of untreated patients. These aneurysms put patients at risk for thrombus formation, myocardial infarction and sudden death. Currently, clinical decisions are made based on anatomy alone, with aneurysm diameter > 8mm as the arbitrary cutoff for anticoagulation therapy, despite a lack of evidence for this choice. We postulate that patient specific hemodynamics may be a better predictor for the risk of thrombosis than maximum diameter alone. To quantify hemodynamics, we performed computational fluid dynamics (CFD) simulations using patient specific models with custom coronary boundary conditions.
