Abstract:
We identified risk factors for infection following transcatheter aortic valve implantation (TAVI); infection occurred in 35 (13.8%) of 253 patients. Variables associated with infection included chronic obstructive pulmonary disease (OR, 1.2; 95% CI, 1.1-1.4), postprocedural hemorrhage (OR, 1.2; 95% CI, 1.0-1.3), and procedure-related stroke (OR, 1.6; 95% CI, 1.3-2.1).

Insights
Infection after transcatheter aortic valve implantation (TAVI) affects 13.8% of patients. Key risk factors include COPD, bleeding, and stroke, aiding in better patient management and outcomes.
Area of Science:
- Cardiology
- Infectious Disease Epidemiology
Background:
- Transcatheter aortic valve implantation (TAVI) is a growing procedure for aortic stenosis.
- Post-procedural infections are a significant complication impacting patient outcomes.
Purpose of the Study:
- To identify and analyze risk factors for infection following TAVI.
- To inform strategies for preventing and managing TAVI-related infections.
Main Methods:
- Retrospective analysis of 253 patients undergoing TAVI.
- Statistical analysis to determine variables associated with infection development.
Main Results:
- Infection occurred in 35 (13.8%) patients.
- Significant risk factors identified: chronic obstructive pulmonary disease (COPD), postprocedural hemorrhage, and procedure-related stroke.
- Odds ratios indicated increased risk with COPD (1.2), hemorrhage (1.2), and stroke (1.6).
Conclusions:
- Specific patient characteristics and procedural complications increase TAVI-associated infection risk.
- Early identification of these risk factors can guide preventative measures.
- Further research may focus on targeted interventions for high-risk patients.
