Background: As one of the most prominent video platforms, YouTube (YT) is used as a source of information for many topics, including the Transcatheter Aortic Valve Replacement (TAVR) procedure. TAVR is a relatively new intervention that provides a minimally invasive alternative to open heart aortic valve replacement. Recently, YouTube began accrediting videos from trusted healthcare sources to combat the spread of misinformation. This policy could benefit the growing number of people accessing the internet for healthcare information. With its vast audience, it is critical that the content present on YT is reliable. Therefore, the educational value of TAVR videos for patients was assessed in this study.

Purpose: The purpose of this study was to assess the educational value of videos regarding Transcatheter Aortic Valve Replacement procedures on YouTube.

Methods: The key word "TAVR" was systematically searched on the YouTube website. Factoring in exclusion criteria, 76 videos were analyzed. Three independent reviewers separately appraised the quality of all videos using the Global Quality Scale (GQS; 5= highest quality, 1= lowest quality). Data such as duration, views, likes, dislikes, days since upload, YT accreditation, and video modality were recorded. View ratio was used to assess video popularity.

Conclusion: Overall, Transcatheter Aortic Valve Replacement YouTube videos were of high educational quality. However, there appears to be a limitation in the quality of animated videos, which could arguably be a more patient friendly modality. Notably, YouTube’s recent accreditation process has successfully laid the foundation to combat the spread of healthcare misinformation. Future studies need to be done in order to assess the long term efficacy of this new policy.
