- W4297457680 abstract "Current literature reports better short-term mortality rates in mitral valve repair over replacement in elderly patients. However, valve durability, postoperative complications, and reintervention rates in these cohorts remain understudied. As such, we aimed to investigate 5-year rates of mortality and reoperation after initial mitral repair or replacement in elderly patients.Using the TriNetX Research Network database, we identified patients aged ≥70 who underwent mitral valve repair or replacement for nonrheumatic mitral insufficiency between January 2010 and December 2020. We 1:1 propensity score-matched cohorts for 33 covariates including demographics, comorbidities, and surgical history. After matching, we compared 5-year mortality and reoperation rates between cohorts using Kaplan-Meier estimates and multivariable Cox proportional hazards models.We compared 823 mitral valve repair patients to a propensity score-matched cohort of 823 mitral valve replacement patients over a 5-year follow-up period. All variables of interest were adequately matched. Cumulative 5-year mortality rate was significantly lower among mitral valve repair patients (17.0% vs. 24.9%; hazard ratio [HR]: 0.66, 95% confidence interval [95% CI]: 0.51-0.87, p < 0.0025). Reoperation rates at 5-year did not differ (2.6% vs. 2,1%; HR: 1.34, 95% CI: 0.67-2.68, p = 0.401).We observed lower 5-year mortality rates and nonsignificantly different reoperation rates among elderly patients with mitral regurgitation undergoing mitral valve repair compared to replacement. Our data support the current understanding that mitral valve repair should be considered as the first treatment line whenever possible, even in elderly patients." @default.
