title: Elective valve-in-valve implantation for migration of a Corevalve in a patient with bicuspid aortic valve stenosis.
abstract: Transcatheter aortic valve implantation for bicuspid aortic valve stenosis (BAVS) is controversial, as its unfavorable anatomy may lead to device dislocation or malfunctioning. If device failure occurs, the bailout intervention can be more complex and technically challenging. We here report a unique case of late migration of a CoreValve (Medtronic, MN) implanted in a patient with BAVS, who was successfully treated with elective valve-in-valve implantation using the first valve as a firm scaffold after waiting for it to adhere at the migrated position. This new strategy may represent a useful salvage option for some patients with prosthesis migration.
