TRI-umphant recovery: A case series of transcatheter tricuspid valve-in-valve replacement for bioprosthetic tricuspid valve stenosis

Abstract

Transcatheter tricuspid valve-in-valve (TViV) replacement is an emerging alternative to repeat surgical intervention for patients with bioprosthetic tricuspid valve stenosis. We present two patients with a history of severe tricuspid regurgitation and bioprosthetic tricuspid valve replacement, one with a history of Ebstein's anomaly and the other with a history of blunt chest trauma. Both patients presented several years later with severe bioprosthetic tricuspid valve stenosis symptomatic with progressive lifestyle limiting dyspnea. Following multi-disciplinary discussion, they were both determined to be of high surgical risk and ultimately managed via a transcatheter approach with TViV replacement.
