Summary
This summary is machine-generated.Pediatric myocardial infarction (MI) is rare. Cardiovascular magnetic resonance (CMR) imaging accurately diagnosed embolic MI secondary to dilated cardiomyopathy (DCM) in a 3-year-old, highlighting advanced imaging
Area Of Science
- Pediatric Cardiology
- Cardiovascular Imaging
- Rare Pediatric Diseases
Background
- Myocardial infarction (MI) is uncommon in young children, often linked to congenital or inflammatory conditions.
- Dilated cardiomyopathy (DCM) can lead to rare complications like embolic MI in pediatric patients.
- Accurate diagnosis of pediatric myocardial injury requires advanced imaging techniques.
Purpose Of The Study
- To present a rare case of embolic MI in a child secondary to DCM.
- To emphasize the diagnostic utility of cardiovascular magnetic resonance (CMR) in pediatric myocardial injury.
- To highlight the importance of advanced imaging in complex pediatric cardiovascular cases.
Main Methods
- Case report of a 3-year-old girl with lethargy and breathlessness.
- Initial investigations included chest X-ray, troponin levels, echocardiography, and ECG.
- Cardiovascular magnetic resonance (CMR) imaging was crucial for definitive diagnosis.
Main Results
- Echocardiography revealed DCM with biventricular thrombi and severely impaired ventricular function.
- CMR excluded active myocarditis and identified transmural MI in the left ventricular apex.
- Findings indicated embolic MI secondary to biventricular thrombi in the context of severe DCM.
Conclusions
- CMR is indispensable for differentiating pediatric myocardial injury etiologies like myocarditis and MI.
- This case highlights the diagnostic challenges and the role of advanced imaging in rare pediatric cardiovascular conditions.
- Embolic MI secondary to DCM is a rare but significant consideration in pediatric cardiology.

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
