Advances in imaging for diagnosis and management of cardiac sarcoidosis

Area of Science:

• Cardiology
• Immunology
• Radiology

Background:

• Sarcoidosis is a multisystem granulomatous disease with frequent cardiac involvement.
• Cardiac sarcoidosis (CS) poses significant risks, including cardiomyopathy and sudden cardiac death.
• Diagnosing CS is difficult due to nonspecific symptoms and the lack of a definitive diagnostic standard.

Purpose of the Study:

• To comprehensively review and compare the diagnostic accuracy of various non-invasive cardiac imaging modalities for CS.
• To analyze the advantages and disadvantages of both established and emerging imaging techniques in CS assessment.

Main Methods:

• Systematic literature review of studies evaluating non-invasive cardiac imaging for CS.
• Comparative analysis of diagnostic performance metrics (sensitivity, specificity) for different imaging modalities.
• Assessment of the strengths and limitations of each imaging technique.

Main Results:

• Non-invasive cardiac imaging plays a crucial role in evaluating patients with suspected or confirmed CS.
• Established modalities show varying degrees of diagnostic utility.
• Emerging techniques offer potential improvements in accuracy and early detection.

Conclusions:

• Accurate diagnosis of CS remains a clinical challenge.
• Non-invasive cardiac imaging is essential for CS assessment, offering a better alternative to low-sensitivity biopsies.
• Further research into emerging imaging modalities is warranted to improve CS detection and patient outcomes.
