Late surgical explantation and aortic valve replacement after transcatheter aortic valve implantation.

Abstract

Transcatheter aortic valve implantation (TAVI) in patients with bicuspid aortic valve disease is associated with higher rates of paravalvular aortic regurgitation, which may require subsequent surgical correction. We report a case of successful late surgical CoreValve explantation 1,389 days after TAVI in a patient with bicuspid aortic valve stenosis and McArdle's disease who developed severe paravalvular aortic regurgitation. We confirm that neoendothelialization and incorporation of the nitinol cage into the aortic wall had occurred at nearly 4 years postimplantation, although explantation with careful endarterectomy could still be performed without requiring simultaneous aortic root replacement.
