Mycobacterium Tuberculosis Infection at Pacemaker Implantation Site

Area of Science:

• Cardiology
• Infectious Diseases
• Medical Device Infections

Background:

• Increasing use of cardiac rhythm management devices leads to higher rates of pacemaker implantation.
• Pacemaker infections represent a growing clinical concern, often associated with Staphylococcus aureus and Staphylococcus epidermidis.
• While common bacterial pathogens dominate, rare infections by mycobacterium species, including tuberculosis, are increasingly recognized.

Observation:

• A case of delayed pacemaker pocket infection with tuberculosis is presented.
• The patient experienced a late-onset infection following pacemaker implantation.
• This highlights a rare but significant etiological agent in device-related infections.

Findings:

• Staphylococcus aureus and epidermidis are the predominant causes of pacemaker infections.
• Mycobacterial tuberculosis is an uncommon but serious cause of implantable cardiac device infection.
• Literature review confirms the rarity of mycobacterial species, particularly tuberculosis, in pacemaker infections.

Implications:

• Delayed pacemaker infections can be caused by unusual pathogens like tuberculosis.
• Clinicians should consider mycobacterial infections in the differential diagnosis of persistent or delayed pacemaker pocket infections.
• This case underscores the importance of a comprehensive diagnostic approach for managing cardiac device infections.
