Dapagliflozin After Transcatheter Aortic Valve Implantation (DapaTAVI)

Pragmatic, controlled, prospective, randomized, open-label (open-label), evaluator-blind clinical trial (PROBE design) that will analyze the benefits of dapagliflozin treatment in patients with severe aortic stenosis discharged after implantation of an aortic valve prosthesis transcatheter (TAVI).

Study Overview

• Status: Completed
• Conditions: Aortic Stenosis; Transcatether Aortic Valve Implantation
• Intervention / Treatment: Drug: Dapagliflozin 10 MG

Detailed Description

Patients discharged after TAVI, with a history of heart failure (HF) plus depressed left ventricular ejection fraction (LVEF ≤ 40%) or diabetes mellitus (DM) or glomerular filtration rate (GFR) between 25 and 75 ml/min/1.73 m2, will be randomized (1:1) before hospital discharge to receive treatment with dapagliflozin 10 mg/day or no dapagliflozin (no placebo).

Only variables available during routine clinical practice will be collected and there will be no additional tests.

The incidence of clinical events and adherence to the dapagliflozin arm will be documented at 2 time-points (3 ± 1 months and 12 months) by phone calls and review of medical records.
