Structural valve deterioration in surgical bioprostheses
may require redo valve surgery, which is associated with
significant operative mortality and poor long-term survival.
As an alternative treatment option, valve-in-valve (ViV)
transcatheter mitral valve replacement (TMVR) has emerged
for patients with symptomatic and severely degenerated
bioprosthetic valves who are at high risk for redo cardiac
surgery. This case report describes the first case of transseptal
valve-in-valve-transcatheter mitral valve replacement in an
85-year-old female patient in Türkiye. The patient had a
degenerated mitral bioprosthesis and was at high surgical
risk. The patient had previously undergone valve-in-valve
transcatheter aortic valve replacement. The procedure was
completed successfully, and there were no complications during
the postprocedural course.
