    A patient developed severe heart constriction after surgery for constrictive pericarditis. Postmortem revealed a unique fibrocartilagenous exoskeleton encasing the heart, suggesting unusual causes for recurrent constriction.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Pathology

    Background:

    • Constrictive pericarditis is a condition where the pericardium becomes stiff, impairing heart function.
    • Pericardiectomy is a surgical procedure to remove the pericardium, aiming to relieve constriction.
    • Recurrent or persistent constriction after pericardiectomy is a rare but serious complication.

    Observation:

    • A patient presented with dependent edema, ascites, and exertional dyspnea seven months post-pericardiectomy.
    • Cardiac catheterization confirmed the return of constrictive physiology.
    • Intraoperative findings revealed extensive mediastinal fibrosis encasing the heart.

    Findings:

    • Postmortem examination identified a unique fibrocartilagenous exoskeleton surrounding both ventricles.

  • This finding represents an unusual and severe form of cardiac constriction.
  • The etiology of this extensive fibrocartilaginous reconstruction remains unclear.

    • Implications:

    • This case highlights the possibility of rare and aggressive forms of pericardial reconstruction after surgery.
    • Further research into the underlying mechanisms of such extensive fibrosis is warranted.
    • Understanding these mechanisms may lead to improved management strategies for post-pericardiectomy constriction.
