Background:
We reviewed frequency, microbiological pattern, predictors, and outcomes of early infections following transcatheter aortic valve replacement (TAVR).
Methods:
Five hundred thirty-nine patients who underwent successful TAVR at a single, high-volume center between January 2014 and December 2019 were enrolled. We defined early infections as occurring within 30-day from TAVR.
Results:
Mean age was 83.5 ± 5.4 years; 230 (42.7%) patients were men. Median follow-up was 12.0 (5.7-18.3) months; 30-day and 1-year death rates were 8/539 (1.5%) and 30/539 (5.6%), respectively. Early infections occurred in 61/539 (11.3%) patients, of whom 2 had infections in two sites. Of the 63 infections, 10 were bloodstream infections (BSI), 5 urinary tract, 27 pulmonary (2 with sepsis), 6 access site infections, 1 enterocolitis, and 14 were clinically diagnosed (no specific site). We observed 31/63 (49.2%) microbiologically-documented infections: Gram+ bacteria were isolated in 12/31 (38.7%), Gram- in 17/31 (54.3%), both Gram+ and Gram- in 2/31 (6.5%); in thirty-two infections no specific pathogen could be isolated (clinically-documented infections). Early infections were more prevalent in patients who died within 30-day (8.2% vs. 0.6%, p < 0.001) or 1-year (14.8% vs. 4.4%, p < 0.001) from TAVR. At multivariable analysis, early infections were independently associated with 30-day (HR: 8.82, 95% CI: 1.11-19.83, p = 0.035) and 1-year mortality (HR: 2.10, 95%CI: 1.28-6.21, p = 0.041). The predictive value for 1-year mortality was maintained even restricting the analysis to documented infections only, or to more severe infections (BSI and pneumonia only) (all p < 0.05).
Conclusions:
Early infections occur in 1/10th of TAVR and are associated with increased short- and long-term mortality. Whereas a causal relationship between early infections and the risk of death cannot be unequivocally proven, careful surveillance of infected patients may improve TAVR results.
Insights
Early infections after transcatheter aortic valve replacement (TAVR) affect about 1 in 10 patients and are linked to higher mortality rates. Close monitoring of TAVR patients with infections may improve outcomes.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Device Technology
Background:
- Transcatheter aortic valve replacement (TAVR) is a crucial procedure for aortic stenosis.
- Understanding early post-TAVR infections is vital for patient management and outcomes.
Purpose of the Study:
- To investigate the frequency, microbiological characteristics, predictors, and outcomes of early infections following TAVR.
- To assess the impact of early infections on short- and long-term mortality after TAVR.
Main Methods:
- A retrospective review of 539 patients who underwent successful TAVR between 2014 and 2019.
- Definition of early infections as those occurring within 30 days post-TAVR.
- Multivariable analysis to identify predictors and associations with mortality.
Main Results:
- Early infections occurred in 11.3% of TAVR patients.
- Pulmonary infections were most common (42.9%), followed by bloodstream infections (15.9%).
- Early infections were independently associated with increased 30-day and 1-year mortality.
Conclusions:
- Approximately 1 in 10 TAVR patients experience early infections, significantly increasing mortality risk.
- While causality is complex, vigilant surveillance of TAVR patients with infections is recommended.
- Improved monitoring may enhance TAVR procedure success rates and patient survival.
