[Transcatheter aortic valve implantation for aortic regurgitation in patients with left ventricular assist device]

Aortic valve regurgitation is a not negligible complication of prolonged support with continuous-flow left ventricular assist device (LVAD) and is associated with recurrence of heart failure and reduced survival. Transcatheter aortic valve implantation has been described as a feasible option in this setting, usually with self-expanding prosthesis. Giving the absence of valvular calcification, a proper prosthesis oversizing should be guaranteed in order to achieve sufficient sealing and avoid prosthesis migration or paravalvular leak. Current self-expanding prosthesis may be too small to fit aortic annulus anatomies without calcification and with the need of significant oversize. We report the first case of 32 mm balloon expandable Myval prosthesis implantation in a patient with LVAD-related aortic regurgitation. Large balloon-expandable prosthesis can be considered when a significant oversize is needed.
