Abstract:: BACKGROUND: Gender- and sex-based disparities in mitral valve disease exist; however the factors associated with these differences are unknown. Identifying these differences is essential in devising mitigating strategies. We evaluated gender and sex differences among patients with severe primary mitral regurgitation (MR) across treatment phases. METHODS AND RESULTS: We conducted a retrospective cohort study of patients with new diagnoses of severe primary MR between 2016 and 2020. We compared multidisciplinary evaluation incidence and 2-year survival between men and women. We analyzed a subgroup meeting class 1 indications for intervention, which includes severe symptomatic MR or severe asymptomatic MR with ejection fraction <60% or left ventricular end-systolic diameter >40 mm. Logistic regression models identified predictors associated with the likelihood of multidisciplinary evaluation. Among 330 patients meeting class 1 indications, women were older (79 versus 76 years, P=0.01) and had higher Society of Thoracic Surgeons risk scores for mitral valve repair than men (2.5% versus 1.4%, P=0.003). Women were less likely to undergo multidisciplinary evaluation (57% versus 84%, P<0.001) and intervention (47% versus 69%, P<0.001) than men. Median days to intervention for women and men were 77 and 43, respectively. Women had a higher 2-year mortality rate than men (31% versus 21%, P=0.035). On a multivariable model, female sex and older age were associated with lower odds of undergoing multidisciplinary evaluation (odds ratio, 0.26; P<0.001; odds ratio, 0.95; P<0.001, respectively). CONCLUSIONS: Women with severe primary MR with class 1 indication for intervention were less likely to undergo multidisciplinary evaluation and intervention and had a longer interval to intervention than men. Survival was comparable after accounting for age and comorbidity differences.
