May favor chordal preservation in mitral replacement; leaves open need for randomized confirmation of durability and outcomes.
Does chordal preservation during mitral valve replacement improve left ventricular size and function compared to resection of the subvalvular apparatus?
Chordal preservation during mitral valve replacement significantly improves postoperative left ventricular ejection fraction and reduces left ventricular dilation compared to complete resection of the subvalvular apparatus.
Straub et al. (1996) studied this question.
