简要总结
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.
详细描述
The CHATEAU Registry is an international, multicenter, observational registry of patients undergoing transcatheter aortic valve replacement. This study will retrospectively analyze consecutive 4,000 patients treated with TAVR at participating centers from January 1, 2021 to December 31, 2025. Follow-up clinical outcomes will be assessed through December 31, 2027.
Eligible patients are adults who underwent TAVR for aortic valve disease. Data will be collected from existing medical records, including baseline demographics, comorbidities, laboratory findings, pre-procedural imaging data, procedural details, device information, post-procedural echocardiographic findings, discharge medications, and clinical follow-up outcomes.
The study aims to evaluate the association between patient-, anatomy-, device-, and procedure-related factors and subsequent clinical outcomes and valve performance. Outcomes of interest may include all-cause death, cardiovascular death, stroke, myocardial infarction, heart failure hospitalization, pacemaker implantation, valve hemodynamic deterioration, aortic valve reintervention, paravalvular regurgitation, and other TAVR-related clinical events.
Because this is a retrospective observational study, all treatment decisions were made according to routine clinical practice at each participating institution. The study does not involve randomization, assignment of treatment, additional procedures, or additional patient visits. All data will be handled in accordance with applicable institutional review board requirements and privacy regulations.
