Multimodality Imaging Approach in the Diagnosis of Constrictive Pericarditis.

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Constrictive pericarditis (CP) stems from persistent pericardial inflammation, presenting with vague symptoms and significantly impacting cardiac function and quality of life.
• Early recognition of CP is vital due to its progressive nature, leading to heart failure.

Purpose of the Study:

• To highlight the critical role of multimodality imaging in the diagnosis, prognosis, and management of constrictive pericarditis.
• To differentiate CP from restrictive cardiomyopathy (RCM) and identify active inflammation.

Main Methods:

• Utilizing echocardiography for hemodynamic assessment and flow patterns.
• Employing Cardiac Computed Tomography (CT) for detailed visualization of pericardial thickening and calcification.
• Leveraging Cardiac Magnetic Resonance (CMR) for anatomical characterization, myocardial-pericardial coupling, and inflammation assessment via late gadolinium enhancement (LGE) and parametric mapping.
• Incorporating Positron Emission Tomography (PET) to detect active inflammation and guide therapy selection.

Main Results:

• Multimodality imaging provides essential diagnostic and prognostic information for CP.
• Echocardiography, CT, CMR, and PET offer complementary insights into pericardial disease and cardiac function.
• Integrated imaging approaches enhance diagnostic precision and risk stratification.

Conclusions:

• Accurate diagnosis and risk stratification of CP are achievable through the integration of multimodality imaging.
• Tailored management strategies based on comprehensive imaging evaluations can improve patient outcomes.
• Advanced imaging techniques are indispensable for optimizing the care of patients with constrictive pericarditis.
