Anterior leaflet procedures during mitral valve repair do not adversely influence long-term outcome
Key result
Anterior mitral leaflet reconstruction yields similar 10-year reoperation rates versus MV repairs without anterior procedures.
- n=558
Why the study?
Do anterior leaflet reconstructive procedures during mitral valve repair adversely affect long-term freedom from reoperation compared to repair without anterior leaflet procedures?

Implication
Observational data associate anterior leaflet reconstruction with comparable durability; leaves open need for randomized confirmation before wider adoption.
Study Design
Type
Cohort (n=558)
Structured PICO
Do anterior leaflet reconstructive procedures during mitral valve repair adversely affect long-term freedom from reoperation compared to repair without anterior leaflet procedures?
P
Population
558 consecutive patients undergoing Carpentier-type mitral valve repair, including 156 with anterior leaflet procedures (mean age 58 years), followed for up to 10 years.
E
Exposure
Anterior mitral leaflet reconstructive procedures during mitral valve repair (including anterior chordal shortening, anterior leaflet resections, resuspension to secondary chordae, and anterior chordal transposition).
C
Comparator
Mitral valve repair without anterior leaflet procedures.
O
Outcome
Freedom from reoperation at 5 and 10 years.hard clinical
Main Result
Absolute Event Rate: 81.2% vs 84.4%
Anterior leaflet reconstructive procedures during mitral valve repair yield immediate and long-term results comparable to procedures without anterior leaflet involvement, demonstrating that aggressive repair of anterior leaflet disease is safe and durable.
Cite This Study
Grossi et al. (1995) conducted a cohort in Mitral valve disease (n=558). Anterior mitral leaflet reconstructive procedures vs. Mitral valve repair without anterior leaflet procedures was evaluated on Freedom from reoperation at 10 years. Anterior mitral leaflet reconstructive procedures during mitral valve repair yielded similar 10-year freedom from reoperation compared to repairs without anterior leaflet procedures (81.2% vs 84.4%).
