Idiopathic dilated cardiomyopathy complicated with brain embolism: report of one case
1Department of Pediatrics, Chung Shan Medical and Dental College Hospital, Taichung, Taiwan, R.O.C.
Insights
Idiopathic dilated cardiomyopathy in children can lead to brain cardioembolism, causing stroke. This case highlights the importance of imaging for diagnosing this rare complication in pediatric patients.
Area of Science:
- Pediatric Cardiology
- Neurology
- Medical Imaging
Background:
- Idiopathic dilated cardiomyopathy (IDCM) is a serious heart condition in children.
- Cardioembolic stroke is a rare but significant complication of pediatric IDCM.
- Diagnostic challenges exist in documenting brain embolism in young children.
Observation:
- A 2-year-old girl with diagnosed IDCM presented with hemiparalysis.
- Imaging revealed left ventricular thrombi on echocardiography and brain embolism on CT scan.
- The clinical course, treatment, and outcome were documented.
Findings:
- This case demonstrates the successful combined use of 2D echocardiography and cranial CT in diagnosing brain cardioembolism secondary to pediatric IDCM.
- Left ventricular thrombi were identified as the source of embolism.
- The patient's hemiparalysis was attributed to the cerebral embolic event.
Implications:
- Highlights the importance of comprehensive cardiac and neurological evaluation in pediatric patients with IDCM.
- Emphasizes the role of advanced imaging techniques in identifying embolic sources and consequences.
- Contributes to the limited literature on cardioembolic stroke in pediatric idiopathic dilated cardiomyopathy.
Abstract:
Idiopathic dilated cardiomyopathy complicated with brain cardioembolism is rarely documented by both 2-dimensional echocardiography and cranial computed tomography in pediatric patients. A 2-year-old girl developed hemiparalysis 15 months after diagnosis of idiopathic dilated cardiomyopathy. The 2-dimensional echocardiograms of left ventricular thrombi, computed tomographic findings of brain embolism, clinical course, treatment and outcome are presented. Previous reports of idiopathic dilated cardiomyopathy in children are reviewed.
