ABSTRACT: Background
Valve-in-valve-in-valve procedures, typically due to late transcatheter valve degeneration, are infrequently reported.Case summary
A 76-year-old man underwent surgical aortic valve replacement in 2016 with a 25-mm Mitroflow bioprosthesis for severe aortic stenosis. Eight years later, he developed acute heart failure due to severe aortic regurgitation from prosthetic degeneration. A valve-in-valve (ViV) procedure was successfully performed using a 25-mm self-expandable Navitor valve. Ten months later, he experienced recurrent symptoms. Imaging revealed late downward migration of the transcatheter valve, resulting in severe paravalvular leak and moderate ventricular dysfunction. The heart team decided to proceed with a repeat ViV procedure using a second self-expan
