Transcatheter aortic‐valve implantation with one single minimal contrast media injection
Why the study?
Does TAVI with a single minimal contrast media injection allow for safe valve implantation in patients with severe aortic stenosis at high risk for acute kidney injury?
Population
n=5 patients with severe aortic stenosis and at high risk for developing contrast-induced nephropathy (CIN)

Implication
May support minimal-contrast TAVI in select high-risk patients; hypothesis-generating and requires prospective validation before practice change.

Intervention
Transcatheter aortic valve implantation (TAVI) via transfemoral access using a self-expanding CoreValve prosthesis with a single minimal contrast media injection
O
Outcome
Device success and major complicationssafety
Performing TAVI with a single minimal contrast injection using a self-expandable valve is feasible and may help preserve renal function in high-risk patients.
