Insights
Kawasaki disease can lead to coronary artery aneurysms. A young patient with trauma-induced myocardial infarction and these aneurysms showed good recovery with conservative treatment.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Medical Case Studies
Background:
- Kawasaki disease is a common cause of acquired heart disease in children.
- Coronary artery abnormalities, including aneurysms, are significant complications.
- Optimal management strategies for acute coronary events in this population remain debated.
Observation:
- A 20-year-old female presented with acute myocardial infarction following blunt chest trauma.
- Imaging revealed coronary artery calcifications and giant left anterior descending aneurysms, indicative of prior Kawasaki disease.
- The patient experienced chest pain, breathlessness, and syncope.
Findings:
- Diagnostic workup, including CT angiography, confirmed myocardial infarction and coronary artery aneurysms.
- A conservative management approach was adopted for the patient.
- The patient remained asymptomatic with preserved left ventricular function at 2-year follow-up.
Implications:
- This case highlights the potential for late cardiovascular complications in individuals with a history of Kawasaki disease.
- Conservative management may be effective for traumatic myocardial infarction in the presence of coronary artery aneurysms.
- Prompt medical intervention can lead to favorable short-term outcomes, preserving cardiac function.
Background:
Kawasaki disease is an acute febrile disease with mucocutaneous and cardiovascular involvement affecting infants and young children. Though coronary artery abnormalities are common in Kawasaki disease, no consensus has been reached regarding the treatment of acute coronary artery diseases in this population.
Case Presentation:
We described a case of myocardial infarction triggered by blunt chest wall trauma in a 20 years old girl. She presented with chest pain and breathlessness with brief syncope, lab results and electrocardiogram findings were consistent with acute myocardial infarction. Chest computer tomography (CT) demonstrated coronary artery calcifications and echocardiography revealed multiple giant left anterior descending aneurysms, suggestive of Kawasaki disease. Subsequent contrast enhanced 3 dimensional coronary computer tomography angiography (CTA) confirmed these findings. We managed this young patient with a conservative strategy. The patient remained symptom free during 2-years follow-ups.
Conclusions:
Prompt medical treatment for traumatic myocardial infarction even with underlying giant coronary artery aneurysms can successfully preserve left ventricular function and prevent remodeling with good short term prognosis.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
