Case Report: Transcatheter aortic valve implantation using balloon-expandable bioprosthesis in patients with severe pure aortic regurgitation on noncalcified native valves: a series of cases

For individuals with pure aortic regurgitation (AR), transcatheter aortic valve implantation (TAVI) is cautiously recommended only for those with a high or prohibitive surgical risk. We aimed to describe the results of a case series of transcatheter implantation of a balloon-expandable aortic valve bioprosthesis (BEV) for the treatment of noncalcified native valve AR.
