What is the clinical evidence from this study?

Study design: Cohort. Population: Degenerative mitral regurgitation (n=53). Intervention: Robotic mitral valve repair (r-MVr) vs. Conventional mitral valve repair (c-MVr). Primary outcome: Postoperative hospital stay (days) (p=0.04).

Short- and Mid-Term Outcomes of Robotic Mitral Valve Repair for Degenerative Mitral Regurgitation in Octogenarians

Key Result

Robotic mitral valve repair in octogenarians significantly reduced postoperative hospital stay compared to conventional repair (12 vs. 13 days, P=0.04) with comparable 30-day mortality.

Key Points

The central aim is to evaluate the safety and feasibility of robotic mitral valve repair in patients aged 80 years and older.

Is robotic mitral valve repair safe and feasible in patients aged ≥80 years with degenerative mitral regurgitation?

Population

Octogenarians (aged ≥80 years) with degenerative mitral regurgitation

Intervention

Robotic mitral valve repair (r-MVr)

Outcome

Short- and mid-term outcomes (safety and feasibility)safety

This study investigates the safety and feasibility of robotic mitral valve repair in octogenarians with degenerative mitral regurgitation.

Limitations

Retrospective single-center analysis with a relatively small sample size
Baseline characteristics of the r-MVr and c-MVr groups were not matched
Follow-up was shorter in the r-MVr group than in the c-MVr group
Concomitant tricuspid annuloplasty and maze procedures were performed less frequently in the r-MVr group
Did not include a direct comparison with transcatheter edge-to-edge repair (M-TEER)

Abstract

Background: Robotic mitral valve repair (r-MVr) offers potential advantages, but its safety and feasibility in patients aged ≥80 years remain unclear.
