[Endocarditis due to Pseudomonas aeruginosa (author's transl)]

Area of Science:

• Cardiology
• Infectious Diseases
• Medical Case Reports

Background:

• Pseudomonas endocarditis is a severe infection, often associated with specific risk factors.
• Biliary origin is an uncommon source for infective endocarditis.
• Osteomyelitis is a rare but serious complication of infective endocarditis.

Purpose of the Study:

• To report a unique case of Pseudomonas endocarditis with biliary origin.
• To highlight the diagnostic utility of echocardiography in such cases.
• To emphasize the poor prognosis associated with left-sided valvular involvement resistant to treatment.

Main Methods:

• Case presentation of a patient with Pseudomonas endocarditis.
• Diagnostic evaluation including echocardiography.
• Review of clinical history and potential complications.

Main Results:

• The patient presented with Pseudomonas endocarditis affecting mitral and tricuspid valves, originating from a biliary source.
• Echocardiography successfully identified vegetation on the tricuspid valve.
• Osteomyelitis was noted as an uncommon complication.
• Differential colony counts did not pinpoint the affected valve.

Conclusions:

• Pseudomonas endocarditis of biliary origin can lead to significant valvular impairment.
• Echocardiography is crucial for diagnosing vegetations in infective endocarditis.
• Left-sided valvular heart disease in this context carries a poor prognosis, especially when refractory to medical management.
