Aspergillus mural endocarditis.
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.
