Aspergillus mural endocarditis
Abstract:
Infectious mural endocarditis is uncommon and not well documented. The clinical setting and pathologic features of five patients with Aspergillus mural endocarditis are described. Leukemia, carcinoma, renal transplantation, and hepatic failure were the primary diseases. Associated conditions include high-dose corticosteroids, cytotoxic therapy, renal failure, gram-negative sepsis, and endotracheal intubation. All patients received prolonged antibiotic therapy or treatment with three or more antibiotics. All had clinically undetected aspergillosis and severe fungal pneumonia. Fungal myocardial abscesses were present in each patient. Aspergillus mural endocarditis developed in more than 40% of patients with cardiac aspergillosis. Endocardial vegetations were contiguous with underlying myocardial infection; yet they may develop initially as a subendocardial focus rather than from a myocardial abscess. Aspergillus mural endocarditis progressed to destroy the mitral valve ring and served as a source of mycotic embolization to vital organs.
Insights
Aspergillus mural endocarditis is a rare complication in critically ill patients, often associated with underlying conditions and undetected fungal infections. This condition can lead to severe valve damage and systemic fungal spread.
Area of Science:
- Infectious Diseases
- Cardiology
- Mycology
Background:
- Infectious mural endocarditis is a rare condition.
- Aspergillus species are increasingly recognized as opportunistic pathogens in immunocompromised individuals.
Purpose of the Study:
- To describe the clinical setting and pathological features of Aspergillus mural endocarditis.
- To investigate the association between Aspergillus endocarditis and underlying cardiac aspergillosis.
Main Methods:
- Case series describing five patients with Aspergillus mural endocarditis.
- Review of clinical data, primary diseases, associated conditions, and treatment regimens.
- Pathological examination of cardiac tissues.
Main Results:
- Patients had severe underlying diseases (leukemia, carcinoma, renal transplantation, hepatic failure) and associated conditions (immunosuppression, renal failure, sepsis).
- All patients had clinically undetected aspergillosis and severe fungal pneumonia with myocardial abscesses.
- Aspergillus mural endocarditis occurred in over 40% of patients with cardiac aspergillosis, often involving the mitral valve and leading to embolization.
Conclusions:
- Aspergillus mural endocarditis is a severe complication in critically ill patients, frequently associated with underlying cardiac aspergillosis.
- The condition can progress to valve destruction and systemic dissemination of the fungus.
- Early recognition and diagnosis are crucial for improved patient outcomes.
