Cardiac Implantable Electronic Device-Related Infection: Updated Review | Chapter 09 | Current Trends in Medicine and Medical Research Vol. 2
In
the 1960s, the first pacemaker with transvenous electrodes was implanted. Over
the years, there have been advances in technology in this area, with the use of
smaller size devices, and with several functions (multifunctional pacemaker).
With this expansion of the indications for implantation of these cardiac
electronic devices (CED), there was an increase of these procedures and 4.2
million patients underwent implantation of these devices between the years
1993-2008. Besides the association between risk of infection and device
replacement, other factors such as male gender, young age, number of
procedures, lack of prophylactic antibiotics and multiple comorbidities have
also been associated with an increased risk of infection of CED. The risk of
infection depends on many factors, including device type and the number of
implantation procedures. In addition to significant morbidity, one-year
mortality is approximately 20%. Therefore, CED infection is an important health
issue. Knowledge of the factors associated with this unfavorable outcome,
clinical manifestations, diagnosis and treatment are very important for proper
approach. This current review presents all these aspects and strategies for the
prevention of infection related to implantable electronic cardiac devices. The
main microbial agent is Staphylococcus. Pocket infection is the most common
presentation, but endocarditis may occur in up 20% of patients. A high index of
suspicion is necessary for diagnosis. Treatment includes antimicrobial therapy
and device removal. Prevention and strategies to minimize the risk factors are
the key to reducing the rates and severity of infection. With the advent of
leadless pacemaker and subcutaneous ICD, this scenario may change.
