Safety and feasibility of zero-contrast transcatheter aortic valve implantation using balloon-expandable valves in patients with aortic stenosis and severe renal impairment: A single-center study
Abstract
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.
