- Abstract: Transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) is a minimally invasive interventional procedure that repairs a valve without removing the old, damaged valve. Instead, a replacement valve is wedged into the location of the native aortic valve. During TAVR, contrast is used for conventional aortic root angiography, positioning of the TAVR valve device, and assessing the peripheral vasculature. Therefore, contrast-induced acute kidney injury (AKI) is a major concern when performing TAVR and is associated with increased mortality in patients with impaired renal function. Although the exact mechanism of post-TAVR AKI is unknown and appears multifactorial, contrast medium has been reported as a major contributing factor. We report a case of zero-contrast TAVR for severe AS in a patient with chronic kidney disease (CKD). The procedure was successfully performed with only fluoroscopic and transesophageal echocardiography (TEE) guidance.
