Findings from isolated pig hearts should not alter chordal management; extends mechanistic insight into mitral apparatus but leaves open human translation.
What are the differential functions of primary and secondary chordae of the anterior mitral leaflet in an isolated pig heart model?
Primary chordae are essential for mitral valve competence, while secondary chordae play a key role in maintaining left ventricular geometry and function.
Obadia et al. (1997) studied this question.
