Infective Endocarditis Rates Lower After TAVR Than SAVR
Infective endocarditis occurred in 2.63% of TAVR patients versus 5.37% after SAVR, suggesting a lower risk with TAVR.
Infective endocarditis (IE) was found to be significantly less common in patients who underwent transcatheter aortic valve replacement (TAVR) compared to those who had surgical aortic valve replacement (SAVR). This conclusion arises from a recent study presented at IDWeek 2026, which analyzed data from a US health record database.
The study reviewed 373,946 aortic valve replacement procedures from January 1, 2018, to December 31, 2025. It included 262,465 TAVR procedures and 111,481 SAVR procedures. Overall, 3.44% of patients developed infective endocarditis, with rates of 2.63% after TAVR and 5.37% after SAVR, indicating a 51% lower rate for TAVR.
Researchers categorized cases into early (within three months post-procedure) and late (after three months), identifying Staphylococcus aureus as the most prevalent bloodstream pathogen in both groups, occurring less frequently after TAVR than after SAVR.
- TAVR: 29.7% of cases
- SAVR: 36.1% of cases
TAVR recipients were typically older; 40.3% were aged 80 or older, compared to 5.9% for SAVR recipients. The study also noted a higher percentage of women among TAVR cases (41.3%) compared to SAVR cases (28.0%).
Though TAVR recipients experienced higher 12-month mortality rates before any endocarditis diagnosis—7.15% after TAVR compared to 5.05% after SAVR—once IE occurred, there was no significant difference in mortality between the two approaches. This suggests that while TAVR presents a lower risk of developing infective endocarditis, the condition remains a serious concern requiring ongoing infection prevention measures after both types of valve replacements.
The findings emphasize the necessity for effective infection control strategies regardless of the type of surgery chosen for aortic valve replacement.
