Acute Kidney Injury Genomics and Biomarkers in TAVR Study

July 24, 2023 updated by: Amanda A Fox, MD, MPH, University of Texas Southwestern Medical Center

Genomic and Biomarker Predictors of Acute Kidney Injury and Other Post-Procedural Outcomes Following Transcatheter Aortic Valve Replacement

In the last decade, transcatheter aortic valve replacement (TAVR) has become an increasingly utilized alternative procedure for replacing a stenotic aortic valve. This study collects clinical information, DNA, blood and urine samples (throughout procedural hospitalization) in order to investigate the incidence of acute kidney injury (AKI) in patients undergoing TAVR and to identify key clinical and procedural predictors of AKI. This study seeks to identify blood and urine biomarkers that can be used for early detection of AKI around the time of the procedure. The study seeks to assess for novel genetic variants associated with development of AKI after TAVR. Finally the study seeks to assess for novel genetic variants and biomarkers that are associated with adverse cardiovascular events after TAVR and to further explore how these events may inter-relate with acute kidney injury.

Study Overview

Detailed Description

This study enrolls patients who have aortic stenosis who undergo TAVR at the University of Texas Southwestern Medical Center University Hospital. Development of post-TAVR AKI defined according to the Kidney Disease: Improving Global Outcomes (KDIGO) SCr based criteria will be ascertained. Patients will be followed during primary hospitalization and during the 5 years following TAVR for adverse kidney outcomes as well as potentially related adverse cardiovascular outcomes. Clinical and procedural data is collected for each study patient. All subjects will have paired blood and urine collection done pre-TAVR, 6 hours after aortic valve prosthesis deployment, and on post-procedure days 1 and 2. Subjects who develop AKI will also have paired blood and urine samples collected on days 3, 4 and 5. Patients receive follow-up questionnaires by mail or email asking about hospitalizations as well as visits to cardiology, nephrology and primary care physicians. Questionnaires will also ask about health-related quality of life using validated study questionnaires. Patient follow-up will occur at regular intervals until 5 years after TAVR procedure.

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

There is a possibility that individual participant data and samples will be de-identified and shared with other cohort study investigators for purposes of replicating biomarker and genetic associations with adverse outcomes.

IPD Sharing Time Frame

Data will become available at the discretion of the sponsor/Dr. Fox. Once enough data has been gathered and analyzed, and the need or DUA requests from other cohort researchers is received.

IPD Sharing Access Criteria

Data will be collected in REDCap, a data management tool used primarily for research and QI. It is a secure, HIPAA-compliant web application. Content is backed up offsite nightly and hosted in a secure environment maintained by UTSW Information Resources. Other cohort researchers will access survey questionnaires via the secure and confidential REDCap webpage with specific view only access. Patient confidentiality is of paramount importance. Data sent outside of UTSW will be de-identified or coded. The "key" to the code (i.e. patient identifying information) will not be provided to the recipient unless a limited dataset is approved for sharing via a data use agreement between Dr. Fox/UTSW and the recipient scientist/recipient scientist's institution.
