Key result
Bileaflet preservation during mitral valve replacement prevented the postoperative decrease in left ventricular ejection fraction that was observed with posterior-leaflet-only preservation.

May favor bileaflet preservation to maintain LVEF after MVR; leaves open confirmation in randomized trials.

Bileaflet preservation during mitral valve replacement prevents the postoperative decline in left ventricular ejection fraction that typically follows posterior-leaflet-only preservation.
Özdemir et al. (2014) conducted a cohort in Mitral valve replacement (n=70). Bileaflet preservation vs. Posterior-leaflet-only preservation was evaluated on Postoperative left ventricular ejection fraction (LVEF) (p=0.001). Bileaflet preservation during mitral valve replacement prevented the postoperative decrease in left ventricular ejection fraction that was observed with posterior-leaflet-only preservation.
