Hypertrophic cardiomyopathy in infancy and childhood
Insights
Hypertrophic cardiomyopathy (HCM) in young children presents with more symptoms and heart failure. Early diagnosis is crucial for managing this condition, as childhood HCM can have a poor prognosis.
Area of Science:
- Pediatric Cardiology
- Cardiovascular Diseases
- Genetics
Background:
- Hypertrophic cardiomyopathy (HCM) is a significant cause of pediatric heart disease.
- Understanding age-related clinical presentations and prognoses in pediatric HCM is essential for effective management.
Purpose of the Study:
- To review clinical, ECG, radiographic, and echocardiographic features of hypertrophic cardiomyopathy in young children.
- To report the prognosis of pediatric patients with HCM over a mean follow-up of 3.5 years.
Main Methods:
- Retrospective review of 15 pediatric patients diagnosed with hypertrophic cardiomyopathy.
- Categorization into two groups: under 2 years (Group 1) and 3-8 years (Group 2).
- Analysis of clinical presentation, ECG, chest radiography, and echocardiography findings.
Main Results:
- Group 1 (under 2 years) exhibited more symptoms and heart failure (7/10 patients) compared to Group 2 (3-8 years, 1/5 patients).
- All patients in Group 1 had ECG abnormalities, while Group 2 patients primarily presented with murmurs.
- Three out of 15 pediatric patients with HCM died during the follow-up period.
Conclusions:
- Pediatric hypertrophic cardiomyopathy presents differently based on age, with younger children experiencing more severe symptoms.
- Accurate and timely diagnosis of HCM in children is critical due to its potential for poor prognosis.
- Medical management strategies should be tailored to the specific clinical presentation and age group.
Abstract:
Hypertrophic cardiomyopathy (HCM) presented in 10 children under 2 years of age (group 1) and in 5 between 3 and 8 years (group 2). The clinical, ECG, chest radiographic and echocardiographic features are reviewed and prognosis over a mean follow-up period of 3.5 years is reported. Patients in group 1 had more symptoms and 7 had evidence of heart failure at some stage; all had ECG abnormalities. Group 2 patients presented with murmurs and only 1 had heart failure. Medical management of these patients is discussed and the importance of accurate diagnosis stressed, since HCM may have a poor prognosis in childhood; 3 out of 15 patients have died.
