Key result
Preservation of the subvalvular apparatus during mitral valve replacement for rheumatic disease did not improve late survival compared to non-preservation (overall 18-year survival 48.0%).

Preservation confers no survival benefit in rheumatic MVR; leaves open effects on other outcomes and requires prospective trials.

Does preservation of the subvalvular apparatus improve long-term survival in patients undergoing mitral valve replacement for rheumatic mitral valve disease?
Preservation of the subvalvular apparatus during mitral valve replacement for rheumatic mitral valve disease does not improve long-term survival compared to non-preservation.
Coutinho et al. (2015) conducted a cohort in Rheumatic mitral valve disease (n=605). Preservation of the subvalvular apparatus (PSVA) vs. Non-preservation of the subvalvular apparatus was evaluated on Long-term survival. Preservation of the subvalvular apparatus during mitral valve replacement for rheumatic disease did not improve late survival compared to non-preservation (overall 18-year survival 48.0%).
