Public interest in Transcatheter Aortic Valve Replacement (TAVR) increased substantially over the last decade, with Google search volume rising by 340% from 2015 to 2025.
Key Findings
TAVR interest surges while SAVR searches decline. Searches for TAVR rose by 340% from 2015 to 2025, while searches for Surgical Aortic Valve Replacement (SAVR) declined by 42% over the same period. The TAVR/SAVR search ratio grew from 0.31 in 2015 to 2.32 in 2025.
The steepest inflection point in TAVR searches occurred after publication of the PARTNER 3 trial (March 2019), with a 156% increase within three months.
Geographic Variations
U.S. states with established TAVR programs generated 3.2 times more TAVR-related searches than low-volume states. Conversely, rural states and regions with fewer TAVR programs displayed higher SAVR interest.
Background
TAVR is a minimally invasive procedure; SAVR requires open-heart surgery. Clinical practice has shifted from reserving TAVR for high-risk patients to using it across all risk levels, with TAVR use doubling between 2015 and 2021.
The study analyzed Google Trends data for "TAVR," "transcatheter aortic valve replacement," "aortic valve surgery," and "SAVR" across three eras:
- Early adoption (2015-2017)
- Expansion (2018-2020)
- Established therapy (2021-2025)
Statistical methods included Wilcoxon tests and Spearman correlations.
Statement
"TAVR is no longer an emerging alternative—it is becoming a foundational approach to care for millions with heart valve disease. Some communities, particularly in rural areas, have less exposure to the latest treatment options, which can delay timely care. By providing targeted education and sharing real-world outcomes, clinicians and educators can help patients make informed decisions and expand access to minimally invasive therapies across all regions."
