This study utilized the Centers for Medicare and Medicaid database to compare late mortality and reintervention rates between robotic and nonrobotic mitral repair in the United States, involving 26,524 isolated first-time procedures. After propensity score matching, results showed similar long-term outcomes for both groups regarding the composite of death or reintervention and all-cause mortality, although robotic repair was associated with lower postoperative atrial fibrillation rates and shorter hospital stays. The findings suggest that robotic mitral repair is a safe option with outcomes comparable to nonrobotic repair.
