CHATEAU Registry: Clinical Outcomes After Transcatheter Aortic Valve Replacement (CHATEAU)

12. juli 2026 opdateret af: Eunpyeong St. Mary's Hospital

Clinical Outcomes in Patients Undergoing Transcatheter Aortic Valve Replacement: The Collaborative Hexagon-Asian Transcatheter Aortic Valve Replacement Union (CHATEAU) Registry

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.

Detaljeret beskrivelse

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.

Studiebefolkning

The study population consists of consecutive adult patients who underwent clinically indicated transcatheter aortic valve replacement (TAVR) for severe native aortic valve disease at participating centers in the CHATEAU Registry. Clinical, imaging, procedural, echocardiographic, and follow-up data are retrospectively collected from routine clinical practice to evaluate long-term clinical outcomes and prosthetic valve performance in a real-world international cohort.

Beskrivelse

Inclusion Criteria:

  • Adults (≥18 years of age).
  • Patients who underwent transcatheter aortic valve replacement (TAVR) for severe native aortic valve disease at participating centers.
  • TAVR performed between January 1, 2021 and December 31, 2025.
  • Availability of baseline procedural and follow-up clinical data in the institutional registry or medical records.

Exclusion Criteria:

  • Patients with insufficient clinical or procedural data for outcome assessment.
