[Hypertrophic obstructive cardiomyopathy in child. About two cases]
Insights
Hypertrophic obstructive cardiomyopathy is a severe heart condition in children, leading to fatal outcomes. Early diagnosis and understanding are crucial for managing this rare disease.
Area of Science:
- Pediatric Cardiology
- Cardiovascular Medicine
Background:
- Hypertrophic obstructive cardiomyopathy (HOCM) is a genetic heart muscle disease.
- It can present in infancy or childhood, often with severe consequences.
Observation:
- Two pediatric cases of HOCM are presented: a 3-month-old infant and an 8-year-old girl.
- The infant presented with cardiac heart failure, while the older child experienced syncope.
- Echocardiography revealed significant ventricular outflow tract obstruction in both cases (100 mmHg and 120 mmHg gradients).
Findings:
- Both patients experienced a fatal evolution of the disease.
- Sudden death occurred at home in both reported cases.
- HOCM in these pediatric patients demonstrated a severe and aggressive clinical course.
Implications:
- This condition highlights the critical need for prompt diagnosis of HOCM in pediatric patients.
- Current therapeutic strategies are insufficient to alter the disease's severe trajectory.
- Further research into effective treatments for pediatric HOCM is warranted.
Abstract:
The authors report two cases of hypertrophic obstructive cardiomyopathy in young girls, age 3 months and 8 years old. The disease manifested itself as a cardiac heart failure in the infant's case and a syncop in the other case. Cardiac echocardiography showed in he first case asymetric hypertrophic cardiomyopathy with ventricular outflow tract obstruction gradient of 100 mmhg, and concentric hypertrophic with 120 mmhg in the second case. Its evolution was fatal in both cases and led to sudden death at home. This disease is severe as no therapeutic treatment can modify its course.
