AIMS: Despite aortic stenosis (AS) relief, patients undergoing transcatheter aortic valve implantation (TAVI) are at increased risk of developing heart failure (HF) within first months of intervention. Sodium-glucose co-transporter 2 (SGLT-2) inhibitors have been shown to reduce the risk of HF hospitalization in individuals with diabetes mellitus, reduced left ventricular ejection fraction and chronic kidney disease. However, the effect of SGLT-2 inhibitors on outcomes after TAVI is unknown. The Dapagliflozin after Transcatheter Aortic Valve Implantation (DapaTAVI) trial is designed to assess the clinical benefit and safety of the SGLT-2 inhibitor dapagliflozin in patients undergoing TAVI.
METHODS: DapaTAVI is an independent pragmatic, controlled, prospective, randomized, open-label blinded endpoint, multicentre trial conducted in Spain, evaluating the effect of dapagliflozin 10 mg/day on the risk of death and worsening HF in patients with severe AS undergoing TAVI. Candidate patients should have prior history of HF admission plus ≥1 of the following criteria: (i) diabetes mellitus, (ii) left ventricular ejection fraction ≤40%, or (iii) estimated glomerular filtration rate between 25 and 75 ml/min/1.73 m2 . A total of 1020 patients will be randomized (1:1) to dapagliflozin vs. no dapagliflozin. Key secondary outcomes include: (i) incidence rate of individual components of the primary outcome; (ii) cardiovascular mortality; (iii) the composite of HF hospitalization or cardiovascular death; and (iv) total number of HF rehospitalizations.
CONCLUSION: DapaTAVI will determine the efficacy and safety of dapagliflozin in a broad spectrum of frail patients after AS relief by TAVI.
