Sex-based differences in mitral valve Re-operation after mitral valve repair: Truth or myth? - 17/11/20
Abstract |
Background |
Outcomes after mitral valve (MV) repair are known to be worse in women. Less is known about sex-based differences in MV repair durability.
Methods |
All adult patients undergoing MV repair from 2002 to 2016 were reviewed. Of 2463 cases, 947 (39%) were women. Re-operation risk was defined as any intervention for repair failure or MV disease progression. Median follow-up was 8.2 years.
Results |
Women were older with higher STS-risk scores and were more likely to have rheumatic disease (RHD). Operative mortality was clinically higher in women (2.7% vs 1.7%; P = 0.09). Although women had significantly higher 10-year re-operation risk (7% vs 4%), adjusted longitudinal analysis showed that this was associated with RHD in women (HR 4.04; P = 0.001). Female sex alone was not a significant predictor (P = 0.21).
Conclusions |
Re-operation following MV repair was infrequent. Women had increased re-operation risk that was largely attributable to their worse preoperative profiles rather than female sex alone.
