Transcatheter aortic valve implantation in patients with a left ventricular assist device: a word of caution.

We describe a patient with a HeartMate 3 left ventricular assist device in whom we attempted transcatheter aortic valve implantation for severe aortic regurgitation. The valve migrated into the left ventricle and lodged on the left ventricular assist device inflow cannula. Caution should be exercised when considering the use of transcatheter aortic valve implantation in patients with an implanted left ventricular assist device, with pure aortic regurgitation.
