Aortic Stenosis, TAVI, Dapagliflozin
Brief summary
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).
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.
Interventions
Dapagliflozin 10 mg (daily oral dose)

Masking description
All events will be adjudicated by the Clinical Events Adjudication Committee (CEAC), without information about the therapy (intervention or control) (blinded endpoint)
Intervention model description
Dapa-TAVI is a pragmatic, controlled, prospective, randomized, open-label blinded endpoint (PROBE design) clinical trial. Patients being discharged after TAVI who meet all inclusion criteria, and none of the exclusion criteria, will be eligible for the enrollment. Patients will be 1:1 randomized to 1 of these 2 arms: * Intervention group: Sodium-glucose cotransporter-2 (SGLT-2) inhibitor therapy with daily oral dose of dapagliflozin 10 mg. * Control group: no SGLT-2 inhibitor therapy with dapagliflozin.
Eligibility
Inclusion criteria
* SEVERE AORTIC STENOSIS UNDERWENT TAVI * PRIOR HEART FAILURE ADMISSION AND ONE OF THE FOLLOWING CRITERIA: 1. Left ventricular ejection fraction ≤ 40% or 2. Diabetes mellitus or 3. Estimated glomerular filtrate rate 25-75 ml/min/1.73 m2
Exclusion criteria
* Known allergy or intolerance to SGLT2 inhibitors. * Concomitant therapy with sulfonylurea or SGLT2 inhibitors.. * Systolic blood pressure \< 100 mmHg or diastolic blood pressure \< 50 mmHg. * An estimated glomerular filtration rate (GFR) below 25 ml per minute per 1.73 m2. * Chronic cystitis and/or recurrent urinary tract infections (2 or more in the last year) * Poor control of diabetes mellitus that requires SGLT-2 inhibitor prescription on discharge according to treating physician judge. * Any medical condition that, in the investigator´s judgment, would seriously limit life expectancy (less than one year). * Pregnant or breast-feeding patients * Patients participating in other clinical trials.

Other
| Measure | Time frame | Description |
|---|---|---|
| Safety endpoints | 1 year | 1. Symptomatic hypotension. Symptomatic hypotension includes postural dizziness with systolic blood pressure \< 100 mmHg, and orthostatic hypotension (defined as a decrease of \>20 mmHg in systolic blood pressure or \>10 mmHg in diastolic blood pressure from a supine to a standing position). 2. Major hypoglycemia. Major hypoglucemia is defined as an event where all the following criteria were confirmed by the investigator: (1) the patient experienced symptoms of severe impairment in consciousness or behaviour; (2) the patient needed external assistance; (3) intervention was needed to treat the hypoglycaemia; and (4) there was prompt recovery of acute symptoms following the intervention. 3. Ketoacidosis. 4. Genital or Urinary Infections 5. Amputation 6. Necrotizing Fasciitis of the Perineum (Fournier's Gangrene) |
| Rate of treatment switch (crossovers) | 1 year | Percentage of patients in the dapagliflozin arm who stop this treatment and percentage of patients in standard care arm who start dapagliflozin therapy |
| Incidence of new Atrial Fibrillation | 1 year | Diagnosis of new Atrial Fibrillation in patients without history of atrial fibrillation at baseline |
| Improvement in NYHA class. | 1 year | Functional class according to New York Heart Association classification |
