Transcatheter aortic valve replacement is increasingly used off-label for native aortic regurgitation in high surgical risk patients, although the absence of annular calcification-particularly after prior valve-sparing aortic root replacement-complicates valve anchoring and increases migration risk. We report a 66-year-old man with severe symptomatic aortic regurgitation after valve-sparing aortic root replacement and hemiarch repair who underwent transcatheter aortic valve replacement. Following deployment of a 29-mm Evolut FX+ valve (Medtronic), valve migration into the left ventricular outflow tract caused severe regurgitation and instability. A second 26-mm SAPIEN 3 Ultra valve (Edwards Lifesciences) was successfully implanted to stabilize the prosthesis, restoring competence and enabling uneventful recovery.
