    Computed tomography (CT) can effectively evaluate constrictive pericarditis by assessing pericardial thickening and vena cava dilatation. This noninvasive imaging technique aids in diagnosing and monitoring the condition, showing improvements after surgery.

    Area of Science:

    • Cardiology
    • Radiology
    • Medical Imaging

    Background:

    • Constrictive pericarditis diagnosis often relies on invasive methods like cardiac catheterization.
    • Limited studies have explored the utility of computed tomography (CT) in evaluating constrictive pericarditis.

    Purpose of the Study:

    • To investigate the effectiveness of plain and contrast-enhanced CT in assessing constrictive pericarditis.
    • To correlate CT findings with clinical diagnosis and surgical outcomes.

    Main Methods:

    • Four patients diagnosed with constrictive pericarditis underwent plain and contrast-enhanced CT scans.
    • ECG-gated CT was performed in one case to assess ventricular dynamics.
    • CT findings were compared to normal pericardial characteristics.

    Main Results:

    • Constrictive pericarditis showed irregular pericardial thickening (>2 mm) and increased CT values compared to normal pericardium (<2 mm).
    • Contrast-enhanced CT revealed significant dilatation of the superior and inferior vena cavae (SVC and IVC).
    • ECG-gated CT demonstrated impaired ventricular expansion; post-surgery, ventricular chambers tended to dilate, and vena cavae dimensions reduced.

    Conclusions:

    • CT is a valuable noninvasive tool for evaluating pericardial thickness and pathology in constrictive pericarditis.
    • CT can assess cardiac chamber and vena cava dilatation, aiding in diagnosis and management.
    • CT findings correlate with disease severity and surgical intervention outcomes.
