Figure 1. Kaplan-Meier analysis of survival after MVr, stratified by type of surgical approach with 95% confidence bands. Log-Rank comparison between strata = 0.004.
Figure 2. Nonparametric estimates of cumulative incidence of the probability of reoperation with death as a competing outcome stratified by approach to MVr (sternotomy, ST, solid line; small right anterior thoracotomy, RAT, dashed line). Grey’s test for equality of cumulative incidence functions between strata, p=0.94.
Figure 3. Nonparametric estimates of cumulative incidence of the probability of progression of mitral regurgitation more than 2 grades with death as a competing outcome stratified by approach to MVr (sternotomy, ST, solid line; small right anterior thoracotomy, RAT, dashed line). Grey’s test for equality of cumulative incidence functions between strata, p=0.53.
Figure 4. Forest plot of multivariable logistic regression model of operative approach. Odds ratio (OR) > 1.0 favors small right anterior thoracotomy approach (bars represent 95% confidence intervals).
Figure 5. Forest plot of propensity adjusted multivariable analysis of mortality, mitral reoperation, and recurrence of MR.
Supplementary Figure 1. Receiver operator curve for multivariable logistic regression model of operative approach.
