Temporal Trends in Mitral Valve Repair Procedures and Outcomes Among Older U.S. Adults

JACC AdvPublished

  • Medicare beneficiaries undergoing mitral valve (MV) repair between 2017 and 2021 were analyzed
  • adjusted Cox models with calendar year as a continuous variable

Authors' conclusion

Between 2017 and 2021, M-TEER utilization increased substantially whereas surgical MV repair declined, resulting in increased overall MV repair utilization. Over the same period, adjusted short-term and midterm mortality improved despite a higher overall comorbidity index.
