Management
TMVR appears to be a reasonable alternative to surgery in patients with failing bioprostheses and rings or mitral valve disease associated with severe mitral annulus calcification, particularly in high surgical risk patients [PMID:33428433].
While valve-in-valve TMVR has more supporting evidence, interventions for valve-in-ring and valve-in-mitral annulus calcification are supported by less robust data, primarily from small case series and voluntary registries [PMID:33428433].
Prognosis & Follow-up
Current results for TMVR in valve-in-ring and valve-in-mitral annulus calcification settings are limited, highlighting the need for more comprehensive long-term follow-up studies [PMID:33428433].
