Hypertrophic cardiomyopathy: case report
1Department of Pathology, Mbarara University of Science and Technology, Uganda.
Insights
Sudden cardiac death in a young adult was linked to undiagnosed hypertrophic cardiomyopathy (HCM). Autopsy revealed heart muscle thickening, a common cause of fatal arrhythmias in inherited heart conditions.
Area of Science:
- Cardiology
- Genetics
- Pathology
Background:
- Sudden cardiac death (SCD) in young adults presents a significant clinical challenge.
- Hypertrophic cardiomyopathy (HCM) is a primary genetic heart muscle disease and a leading cause of SCD in this demographic.
- Autosomal dominant inheritance patterns are observed in approximately 50% of HCM cases.
Observation:
- A case report details a 19-year-old male with sudden, unexplained death.
- Autopsy revealed significant interventricular septum and left ventricle hypertrophy.
- These findings are pathognomonic for hypertrophic cardiomyopathy (HCM).
Findings:
- The autopsy confirmed hypertrophic cardiomyopathy (HCM) as the underlying cause of death.
- HCM can be associated with genetic syndromes like neurofibromatosis and pheochromocytoma.
- The condition is strongly linked to severe cardiac arrhythmias and sudden mortality.
Implications:
- Highlights the importance of recognizing subtle cardiac abnormalities in young individuals.
- Undiagnosed HCM poses a critical risk for sudden cardiac death.
- Genetic counseling and screening are vital for families with a history of HCM or unexplained SCD.
Abstract:
A case report of a 19 year old young adult male who died suddenly without any apparent clinical cause is presented. Autopsy examination revealed hypertrophied interventricular septum and left ventricle suggestive of a hypertrophic cardiomyopathy (HCM). About 50% of hypertrophic cardiomyopathies are inherited as autosomal dominant disorder, sometimes associated with neuroectodermal syndromes, such as neurofibromatosis and pheochromocytoma. HCM is one of the common causes of severe arrhythmias and sudden death.
