Key result
The modified total leaflet preservation technique significantly improved postoperative left ventricular ejection fraction (57.92%) compared to posterior leaflet preservation (56.76%) and no preservation (55.55%).
Why the study?
Mitral valve replacement with total leaflet preservation yields good results, but is limited by patient-valve mismatch.
Does the modified total leaflet preservation technique improve short-term echocardiographic outcomes and reduce complications compared to posterior or no leaflet preservation in patients undergoing mitral valve replacement for rheumatic disease?

The modified total leaflet preservation technique during mitral valve replacement for rheumatic disease improves short-term left ventricular dimensions and ejection fraction compared to posterior or no leaflet preservation.
Guo et al. (2019) conducted a cohort in Rheumatic mitral valve disease (n=180). Modified total leaflet preservation technique vs. Posterior leaflet preservation and no leaflet preservation techniques was evaluated on Postoperative left ventricular ejection fraction (LVEF) at 6 months (p=<0.001). The modified total leaflet preservation technique significantly improved postoperative left ventricular ejection fraction (57.92%) compared to posterior leaflet preservation (56.76%) and no preservation (55.55%).
