Postoperative acute renal failure is a frequent complication after a Transcatheter Aortic Valve Implantation (TAVI). The current practice cannot predict Acute Kidney Injuries (AKI) early enough to prevent an organic dysfunction triggering, consequently, cortical tubular necrosis. Several recent studies in cardiac surgery have shown that sonographic criteria, the Renal Resistive Index (IRR), and a urinary biomarker, the NephroCheckâ„¢, could predict AKI promptly. These markers, sonographic and biologic, have both the advantage to be non-invasive and easy to perform. Each marker seems to have sensitivity and specificity to predict AKI promptly after cardiac surgery. Therefore, the IRR and the NephroCheckâ„¢ test could become essential tests to guide clinicians in determining rapidly whether a patient will develop AKI after a TAVI procedure. However, so far, no study has tested the NephroCheckâ„¢ in patients undergoing TAVI. Therefore, the aim of this prospective observational study will be first to determine the effectiveness of the NephroCheckâ„¢ to predict AKI at an early stage after a TAVI procedure. The secondary outcome will be to compare the NephroCheckâ„¢ with the RRI in predicting at an earlier stage than the traditional method an AKI.

Effectiveness of the NephroCheckâ„¢ test to detect AKI after TAVI
Timeframe: Evolution of the Nephrocheck test from the time 0 to time 2.(Time 0: at inclusion before the TAVI / Time 1: NephroCheckâ„¢ Test at the first micturition post TAVI / Time 2: NephroCheck testâ„¢ on the first post operative day at the first micturition.)
