Brief Summary

Transcatheter aortic valve implantation (TAVI) is a standard procedure for severe aortic stenosis patients with moderate or higher risk of surgery. Several studies have reported the adverse effects of blood disorders, such as anemia and iron deficiency, on the prognosis of patients undergoing TAVI, and many other studies have been conducted to find ways to prevent them. Iron isomaltoside, the latest intravenous iron supplement, can effectively replenish iron store with a single high-dose injection. Research has shown that a preoperative single high-dose iron isomaltoside (1000mg) safely increased hemoglobin levels after surgery in patients undergoing cardiac surgery. However, there have been no studies on the effect of ultra-short-term use of intravenous iron supplements prior to TAVI procedure. Therefore, we investigate the effect of a single high-dose of iron isomaltoside (20mg/kg, maximum dose: 1g) on the hemoglobin concentration after the TAVI.

Outcome Measures

Primary Outcomes (4)

  • Hemoglobin (Hb) concentration

    Compare the Hb concentrations between the Iron isomaltoside group and the Control group.

    1~3 days before TAVI (Baseline)

  • Hemoglobin (Hb) concentration

    Compare the Hb concentrations between the Iron isomaltoside group and the Control group.

    within 5 minutes after TAVI

  • Hemoglobin (Hb) concentration

    Compare the Hb concentrations between the Iron isomaltoside group and the Control group.

    2 days after TAVI

  • Hemoglobin (Hb) concentration

    Compare the Hb concentrations between the Iron isomaltoside group and the Control group.

    2 weeks after TAVI (when the participant has not been discharged for 2 weeks) or 1st outpatient visit after TAVI (when the participant has been discharged within 2 weeks)

Secondary Outcomes (11)

  • Transfusion requirement

    1~3 days before TAVI (Baseline)

  • Transfusion requirement

    During hospitalization period after TAVI, an average of 1 week

  • Transfusion requirement

  • Functional performance - Essential frailty toolset (EFT)

    1~3 days before TAVI (Baseline)
