Abstract:
A 33 year old female had febrile aplasia following a first chemotherapy treatment for acute T lymphoid leukaemia. She was transferred to intensive care for acute respiratory distress due to bilateral pneumonia with Stenotrophomonas maltophilia septicaemic shock. After an initial improvement with antibiotic treatment, she developed multiple necrotic cutaneous lesions. A skin biopsy showed the presence of Aspergillus flavus in large quantities in the vascular lumina. Echocardiography revealed a voluminous vegetation on the mitral valve supporting aspergillus endocarditis. Despite antifungal treatment, shock and coma developed rapidly. Cerebral CT scan suggested multiple septic emboli. Within several hours, the scenario progressed towards multiorgan failure leading the death of the patient. Aspergillus endocarditis is exceptional and usually only occurs in immunosuppressed patients. The diagnosis is difficult, and the prognosis is appalling with a mortality greater than 90% despite treatment.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
