Insights
Thrombolytic therapy with tissue-type plasminogen activator successfully dissolved coronary artery thrombi in a child with Kawasaki disease. This treatment may prevent heart attacks and sudden death in affected pediatric patients.
Area of Science:
- Pediatric Cardiology
- Cardiovascular Research
- Thrombosis Management
Background:
- Kawasaki disease is a leading cause of acquired heart disease in children.
- Coronary artery aneurysms and thrombi pose a significant risk of myocardial infarction and sudden death.
- Limited therapeutic options exist for managing mural thrombi in pediatric coronary aneurysms.
Observation:
- A 7-month-old boy with Kawasaki disease presented with massive mural thrombi in coronary aneurysms.
- Magnetic resonance imaging visualized thrombi in both proximal and distal coronary arteries.
- The thrombi resolved following intravenous and intracoronary thrombolytic therapy.
Findings:
- Tissue-type plasminogen activator effectively treated mural thrombi in coronary aneurysms caused by Kawasaki disease.
- Complete resolution of thrombi was confirmed by follow-up magnetic resonance imaging.
- The therapeutic approach demonstrated safety and efficacy in this pediatric case.
Implications:
- Intravenous and intracoronary thrombolytic therapy with tissue-type plasminogen activator is a potential strategy for Kawasaki disease patients with coronary thrombi.
- This treatment may reduce the risk of acute myocardial infarction and sudden cardiac death in pediatric populations.
- Further research is warranted to establish the long-term efficacy and safety of thrombolytic therapy in Kawasaki disease.
Abstract:
Thrombolytic therapy using tissue-type plasminogen activator was performed in a 7-month-old boy with massive mural thrombi in large coronary aneurysms due to Kawasaki disease. Magnetic resonance imaging successfully demonstrated mural thrombi in both proximal and distal coronary aneurysms and their disappearance after thrombolytic therapy. We conclude that for preventing acute myocardial infarction and sudden death intravenous and intracoronary thrombolytic therapy with tissue-type plasminogen activator may help in infants and children with Kawasaki disease who have thrombi in coronary aneurysms.
