What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 4 studies follow an already-approved treatment in real-world conditions to monitor long-term safety and effectiveness.

This trial targets 402 participants in total. It began in 2024-08-12 with a primary completion date of 2028-07.

Brief Summary

The aim of the open-label, randomized controlled superiority IRON TAVI trial is to investigate whether intravenous iron therapy (ferric carboxymaltose) improves Health-Related Quality of Life (HRQOL) in patients with severe aortic stenosis (AS) and iron deficiency (ID), undergoing transcatheter aortic valve implantation (TAVI). The main questions it aims to answer are: 1. Does intravenous iron therapy improve HRQOL after TAVI in patients with severe AS and ID compared to no intravenous iron therapy (standard of care)? 2. Can intravenous iron therapy enhance exercise capacity, as measured by the 6-minute walk test, after TAVI in patients with severe AS and ID compared to no intravenous iron therapy (standard of care)? The intervention group (receiving iron therapy after TAVI) will be compared to the control group (receiving no iron therapy after TAVI (standard of care)). Participants will: * Provide written informed consent * Be randomly assigned to one of two groups: 1. Intervention group: receiving intravenous iron therapy after TAVI (1-3 administrations in the course of 12 weeks) 2. Control group: receiving standard of care (= no iron therapy) * Complete assessments of HRQOL and the 6-minute walk test at baseline and week 24 after TAVI. * During follow-up visits, other clinical parameters will be collected (i.e. laboratory status, mortality status, adverse clinical events)
