Although surgical aortic valve replacement (SAVR) remains the recommended treatment for patients younger than 65, recent U.S. trends show growing use of transcatheter aortic valve replacement (TAVR) in this population. This study used Truveta platform data to evaluate temporal and geographic patterns of TAVR use among patients under 65. Inclusion criteria identified individuals undergoing isolated TAVR or SAVR without concurrent cardiac procedures. Analysis revealed increasing proportions of TAVR from 2012 to 2019, followed by a decline through 2024. Attempts to determine rural-urban variation were limited by restricted geographic granularity and a nontransparent “Rurality Indicator” metric. The dataset’s geographic incompleteness (30% blocked) prevented definitive conclusions regarding spatial variation. Findings highlight the need for more granular, validated data platforms to analyze guideline deviations and understand procedural selection patterns in younger patients.
