Insights
Transthyretin familial amyloidosis, a rare heart condition, is challenging to diagnose. This case highlights a diagnostic algorithm combining clinical, imaging, and genetic tests for accurate identification.
Area of Science:
- Cardiology
- Genetics
- Medical Diagnostics
Background:
- Familial amyloidosis is a rare, often undiagnosed condition.
- Transthyretin amyloidosis can lead to chronic heart failure.
- Early diagnosis is crucial for effective management.
Observation:
- A patient presented with chronic heart failure, low ejection fraction, and left ventricle hypertrophy.
- Echocardiography and cardiac MRI revealed characteristic granular sparkling.
- Myocardial biopsy and genetic testing were performed.
Findings:
- The patient was diagnosed with transthyretin familial amyloidosis.
- A specific Glu54Gln gene mutation was identified as the cause.
- A comprehensive diagnostic algorithm was employed.
Implications:
- This case underscores the importance of a multi-modal diagnostic approach.
- Accurate diagnosis of familial amyloidosis enables timely intervention.
- Understanding genetic mutations aids in familial amyloidosis diagnosis and counseling.
Abstract:
Familial amyloidosis is a rare type of amyloidosis, difficult to diagnose. We present the case of a woman with chronic heart failure. Low ejection fraction and concentric left ventricle hypertrophy with granular sparkling were seen by echocardiography and cardiac magnetic resonance imaging. Based on myocardial biopsy and genetic tests, the diagnosis of transthyretin familial amyloidosis, secondary to the Glu54Gln gene mutation, was made. The presentation contains the diagnostic algorithm used in the case of our patient, including clinical, biochemical, imaging, histological and genetic examinations, for the purpose of a complete diagnosis.
