Mitral valve endocarditis caused by Pseudomonas aeruginosa: a case report

Area of Science:

• Cardiology
• Infectious Diseases
• Medical Microbiology

Background:

• Pseudomonas aeruginosa (PA) endocarditis traditionally affects the right side of the heart with a favorable prognosis.
• Recent trends indicate a rise in nosocomial PA endocarditis, with increased involvement of left-sided valves (aortic and mitral).
• Left-sided PA endocarditis is uncommon but associated with severe complications and elevated mortality.

Observation:

• A high-risk patient with coronary artery disease and left-ventricular dysfunction presented with mitral valve endocarditis.
• The infection was caused by Pseudomonas aeruginosa.
• Complications included splenic abscess formation.

Findings:

• Successful treatment of Pseudomonas aeruginosa mitral valve endocarditis was achieved in a complex patient.
• The treatment strategy effectively managed both the valvular infection and the splenic abscess.

Implications:

• This case underscores the evolving clinical landscape of PA endocarditis, emphasizing the need for vigilance in left-sided infections.
• Successful management in high-risk individuals suggests that aggressive treatment strategies can overcome significant complications.
• Further research into optimal therapeutic approaches for complex left-sided PA endocarditis is warranted.
