How should i treat a left ventricular outflow tract-migrated balloon-expandable transcatheter heart valve?

Abstract

BACKGROUND: A high surgical risk patient with severe aortic stenosis underwent transcatheter aortic valve implantation. INVESTIGATION: Transcatheter aortic valve implantation was performed uneventfully. DIAGNOSIS: Early after the procedure, echocardiography study and aortography indicated that the implanted valve migrated into the left ventricular outflow tract. MANAGEMENT: A second transcatheter aortic valve was implanted inside the migrated valve (TAV-in-TAV) while securing the position of the migrated valve.
