Isolated pulmonary valve endocarditis due to Pseudomonas aeruginosa

Area of Science:

• Cardiology
• Infectious Diseases
• Medical Microbiology

Background:

• Isolated endocarditis of the native pulmonary valve is uncommon.
• Predisposing factors typically include intravenous drug abuse, alcohol abuse, sepsis, endovascular infections, or congenital heart disease.

Observation:

• This report details a rare case of isolated pulmonary valve endocarditis caused by Pseudomonas aeruginosa.
• The infection occurred in a patient without the commonly associated predisposing factors.
• The origin of the infection is suspected to be nosocomial.

Findings:

• Native pulmonary valve infection by Pseudomonas aeruginosa in the absence of predisposing factors has not been previously documented in medical literature.
• This case highlights a novel presentation of pulmonary valve endocarditis.

Implications:

• Early diagnosis of this rare entity is critical for patient survival.
• The increasing number of invasive hospital procedures may contribute to a rise in such infections.
• Further research is needed to understand the mechanisms and risk factors for nosocomial pulmonary valve endocarditis.
