Abstract:
Kawasaki disease (KD) is a systemic inflammation of the blood vessels seen in children. It is the leading cause of acquired heart disease. Coronary artery aneurysm (CAA) is the most concerning complication, associated with long-term morbidity and mortality. This systematic review examined long-term outcomes of CAAs in KD, with emphasis on regression, complications, and the role of medical and surgical interventions. A total of 21 studies involving 10,922 patients were reviewed. The incidence of CAAs ranged from 3%-27%, mostly affecting infants under 6 months. Small and moderate aneurysms regressed in the majority of cases (>80%), whereas giant aneurysms were less likely to regress. Complications included thrombosis, myocardial infarction, major adverse cardiac events, and cardiac death. Early treatment with intravenous immunoglobulin (IVIG) enhanced the likelihood of regression. Aneurysms in the left anterior descending artery were less likely to regress, suggesting an anatomical influence. Coronary artery bypass grafting was the most common surgical intervention. Early and aggressive management with IVIG, with escalation to steroids or biologics when required, remains the preferred approach. Surgical intervention is sought for giant or persistent aneurysms. These findings emphasize the importance of timely diagnosis, risk stratification, and the establishment of standardized guidelines to optimize long-term care and surveillance of patients with KD.
