Insights
Left ventricular noncompaction (LVNC) is a rare genetic cardiomyopathy. Early diagnosis and intervention are crucial for managing this condition and reducing associated risks.
Area of Science:
- Cardiology
- Genetics
- Pathology
Background:
- Left ventricular noncompaction (LVNC) is a rare congenital abnormality.
- It is classified as a genetic cardiomyopathy, stemming from disrupted endomyocardial development.
- The mechanisms behind left ventricular dysfunction in LVNC, often appearing after age 40, remain poorly understood.
Purpose of the Study:
- To present a case of LVNC in an adult patient.
- To highlight the diagnostic features and management of LVNC.
- To emphasize the importance of physician awareness regarding LVNC.
Main Methods:
- A case report of a 60-year-old woman with shortness of breath.
- Diagnostic procedures included echocardiography, cardiac catheterization, and endomyocardial biopsy.
- Histological examination revealed endomyocardial fibrosis.
Main Results:
- Echocardiography showed noncompacted endocardium, indicative of LVNC.
- Cardiac catheterization and viral studies were normal.
- Histology confirmed endomyocardial fibrosis without disarray.
Conclusions:
- LVNC requires increased physician awareness due to high misdiagnosis rates and complications.
- Prompt diagnosis and intervention can significantly reduce morbidity and mortality.
- Family screening is recommended for individuals diagnosed with LVNC.
Background:
Left ventricular noncompaction (LVNC) is a rare congenital abnormality. It is currently classified as a genetic cardiomyopathy and results from early arrest of endomyocardial morphogenesis. The pathophysiology of left ventricular dysfunction, which becomes apparent beyond the 4th decade of life, is unclear.
Case Report:
We report a case of 60-year-old woman who presented with shortness of breath and showed noncompacted endocardium on echocardiography. Cardiac catheterization and viral studies were unremarkable. Histology revealed endomyocardial fibrosis without disarray. She was subsequently diagnosed with LVNC and treated with medications.
Discussion:
Cardiologists and other physicians should be aware of LVNC due to its high likelihood of misdiagnosis and associated high complication rates. Early diagnosis, intervention and screening among family members can decrease the morbidity and mortality associated with LVNC.
