Zero-Contrast Transcatheter Aortic Valve Implantation vs. Standard Practice: Periprocedural and Long-Term Clinical Outcomes.
J Clin Med
September 2024
Interventional Cardiology Unit, GVM (Gruppo Villa Maria) Care & Research, Maria Cecilia Hospital, 48033 Cotignola, Italy.
: We aimed to compare the procedural efficacy and long-term clinical results of a totally contrast-free Transcatheter Aortic Valve Implantation (TAVI) procedure (i.e., contrast dye was not used for either the pre-procedural assessment or during the procedure) to those of standard practice in patients with severe renal dysfunction.

Background: Aortic stenosis (AS) and chronic kidney disease (CKD) can coexist. Repeat exposure to contrast media in patients undergoing transcatheter aortic valve implantation (TAVI) has latent mortality risks and increased risk for acute kidney injury. We aimed to assess our "zero-contrast TAVI" protocol for patients with advanced CKD.

Background: Acute kidney injury (AKI) is frequently observed after transcatheter aortic valve implantation (TAVI). Of note, it is associated with a threefold increase in all-cause and cardiac death. We propose a new non-contrast strategy for evaluating and performing the TAVI procedure that can be especially valuable for patients with aortic stenosis (AS) and chronic kidney disease (CKD) to prevent AKI.

Department of Interventional Cardiology, Hospital Israelita Albert Einstein, São Paulo, Brazil.
Background: Candidates for transcatheter aortic valve implantation (TAVI) are currently evaluated using computed tomography angiography and invasive cardiac catheterization as an essential part of case selection and pre-procedure interventional planning. However, both imaging methods utilize iodinated agents, which may cause contrast-induced nephropathy, particularly in patients with baseline renal dysfunction. This study aimed to describe a zero-contrast imaging protocol for pre-TAVI evaluation in patients with advanced renal impairment.
