Design outcomes

Primary

Measure	Time frame
AKI based on the Valve Academic Research Consortium-3 (VARC-3), which closely follows the KDIGO criteria (stages 1 to 3)	—

Secondary

Measure	Time frame
1. Association of individual components of VEXUS Score with Renal Outcome. 2. Association of Ultrasound markers of Venous Congestion with Doppler based renal resistive index (RRI) in Trans Aortic Valve Replacement (TAVR) patients. 3. Association of Ultrasound markers of Venous Congestion and echocardiographic evaluation of the right heart function.	—
