Key result
Chordal replacement using a new double-headed mitral leaflet retractor achieved a 98.2% reoperation-free survival and 88.0% freedom from moderate-to-severe mitral regurgitation at 5 years.

Supports feasibility of novel retractor in anterior prolapse; leaves open need for comparative trials before wider use.
Kashiyama et al. (2014) conducted a cohort in degenerative anterior mitral leaflet prolapse (n=55). chordal replacement using a new double-headed mitral leaflet retractor was evaluated on Reoperation-free survival at 5 years. Chordal replacement using a new double-headed mitral leaflet retractor achieved a 98.2% reoperation-free survival and 88.0% freedom from moderate-to-severe mitral regurgitation at 5 years.
