Inclusion criteria

Inclusion criteria: Patients scheduled to undergo transcatheter aortic valve implantation (TAVI) at our institution Patients capable of providing written informed consent

Exclusion criteria

Exclusion criteria: Patients with pacemaker or implantable cardioverter-defibrillator (ICD), in whom bioelectrical impedance analysis (BIA) is contraindicated Emergency cases Patients on chronic dialysis Valve-in-valve cases (redo transcatheter valve implantation within a previously implanted bioprosthetic valve) Patients undergoing TAVI via non-transfemoral approaches Patients converted to open surgical aortic valve replacement

Design outcomes

Primary

Measure	Time frame
The primary outcome is all-cause mortality within 1 year after TAVI. Mortality will be ascertained from hospital electronic medical records, outpatient clinic records, and, if necessary, telephone follow-up. The time point of evaluation is defined as one year after the date of the TAVI procedure.	—
