Echocardiographic screening results in patients with tuberous sclerosis complex

Area of Science:

• Cardiology
• Genetics
• Medical Imaging

Background:

• Tuberous sclerosis complex (TSC) is a genetic disorder with multisystemic manifestations.
• Cardiac involvement in TSC is recognized, but the frequency of specific echocardiographic findings requires further elucidation.

Purpose of the Study:

• To determine the prevalence of abnormal echocardiographic findings in patients diagnosed with tuberous sclerosis complex.
• To identify the most common echocardiographic abnormalities in this patient cohort.

Main Methods:

• Retrospective cohort study of 56 patients with TSC undergoing echocardiographic screening between 1995 and 2003.
• Independent review of echocardiographic reports by two research scientists.
• Statistical analysis including descriptive statistics, Mann-Whitney U test, and chi(2) test.

Main Results:

• Abnormal echocardiographic findings were present in 39% (22 out of 56) of patients.
• The most frequent abnormality was focal intramyocardial echogenicity, observed in 29% (16 out of 56) of patients.
• The clinical significance of increased intramyocardial echogenicity in TSC remains undetermined.

Conclusions:

• Echocardiographic abnormalities are a common finding in patients with tuberous sclerosis complex.
• Increased intramyocardial echogenicity is a prevalent echocardiographic abnormality in TSC patients.
• Further research is needed to understand the clinical implications of these cardiac findings in TSC.
