Endocarditis due to Streptococcus agalactiae presenting with myositis.

Area of Science:

• Cardiology
• Infectious Diseases
• Rheumatology

Background:

• Endocarditis is a serious infection affecting heart valves.
• Streptococcus agalactiae, typically associated with neonatal infections, can cause endocarditis in adults.
• Myositis, inflammation of muscle tissue, is an uncommon presentation of endocarditis.

Observation:

• A patient presented with symptoms suggestive of endocarditis.
• Diagnostic evaluation revealed aortic valve involvement by Streptococcus agalactiae.
• The patient exhibited myositis, notably without myocardial involvement.

Findings:

• Successful treatment of aortic valve endocarditis caused by Streptococcus agalactiae.
• Emergency aortic valve replacement was necessary for patient management.
• The patient experienced a favorable recovery post-intervention.

Implications:

• This case highlights the diverse clinical manifestations of Streptococcus agalactiae endocarditis.
• It underscores the importance of considering unusual presentations like myositis in endocarditis diagnosis.
• Early surgical intervention is crucial for favorable outcomes in severe aortic valve endocarditis.
