Insights
Desmin cardiomyopathy, a rare cause of heart failure, presents diverse phenotypes. This case highlights adolescent onset and evolving clinical features, complicating early diagnosis and treatment.
Area of Science:
- Cardiology
- Genetics
- Rare Diseases
Background:
- Desmin cardiomyopathy is a rare genetic disorder affecting the heart muscle.
- It is characterized by the accumulation of desmin protein aggregates within cardiomyocytes.
- Clinical presentation varies, often including heart failure, conduction abnormalities, and neuromuscular issues.
Observation:
- This report details the first documented case of desmin cardiomyopathy manifesting in adolescence.
- The patient exhibited a dynamic clinical course with evolving phenotypes over time.
- The case presented significant diagnostic challenges due to its varied manifestations.
Findings:
- Desmin cardiomyopathy can present with diverse phenotypes, including hypertrophic, restrictive, and arrhythmogenic patterns.
- Early manifestation in adolescence is possible, contrary to typical childhood or adult presentations.
- The transformation of phenotypes over time complicates early and accurate diagnosis.
Implications:
- This case underscores the importance of considering desmin cardiomyopathy in adolescents with unexplained heart conditions.
- Recognizing the variable and evolving phenotypes is crucial for timely diagnosis and management.
- Further research into desmin cardiomyopathy's diverse clinical spectrum is warranted to improve patient outcomes.
Abstract:
Desmin cardiomyopathy is a rare cause of congestive heart failure. Its clinical manifestation in adulthood often is associated with conduction disorders and a neuromuscular phenotype. Only a few cases have been reported, with early manifestation in childhood mostly due to severe cardiomyopathy dilation and conduction abnormalities. However, the disease can result in the variety of clinical phenotypes, including hypertrophic, restrictive, and arrhythmogenic cardiomyopathy. This report describes the first case of desmin cardiomyopathy with early manifestation in adolescence and transformation of several clinical phenotypes over time, representing sufficient difficulties for the correct clinical diagnosis and treatment of the disease at an early stage.
