Device-related infections (DRI) affect 4.3% of patients with cardiac resynchronization therapy (CRT) devices. Key predictors include longer procedure times, dialysis, re-intervention, and CRT-ICD implantation.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Devices
Background:
- Device-related infections (DRI) are a significant complication following cardiac resynchronization therapy (CRT) implantation.
- Understanding the prevalence and predictors of CRT DRI is crucial for patient management.
Purpose of the Study:
- To determine the prevalence of DRI in patients with CRT devices.
- To identify factors that predict the occurrence of CRT DRI.
Main Methods:
- A retrospective analysis of 303 patients who underwent CRT implantation between 2001 and 2007.
- Univariate and multivariate analyses were performed to identify predictive factors for DRI.
Main Results:
- The overall prevalence of CRT DRI was 4.3%, with endocarditis, pocket erosion, and pocket abscess being the most common types.
- Independent predictors of DRI included longer procedure time, need for dialysis, re-intervention, and initial implantation of a CRT-ICD system.
Conclusions:
- The incidence of CRT DRI is approximately 1.7% per year.
- Identifying patients at higher risk based on procedure time, dialysis status, re-intervention history, and device type can inform pre-operative risk-benefit assessments.

The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
