Summary

This study is a multicenter, retrospective registry study using the CHATEAU Registry. The study will evaluate patients who underwent transcatheter aortic valve replacement between January 2021 and December 2025. The purpose of the study is to assess clinical outcomes and valve performance after TAVR in real-world practice, with a focus on procedural strategies, valve-related factors, and long-term outcomes. Patient clinical information, imaging findings, procedural data, echocardiographic results, and follow-up outcomes will be collected from existing medical records. No additional intervention, treatment, or study-specific visit will be performed.
