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 and urine output 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.
