 Effects of a saddle shaped annulus on mitral valve function and chordal force distribution: an in vitro study by Jorge Hernan Jimenez and others

Annals of Biomedical Engineering 31(10), 1171–1181 (2003), DOI 10.1114/1.1616929. Abstract: eleven human mitral valves in a left-heart simulator with flat versus saddle annular configurations; chordal force transducers in six experiments. Shape changed chordal force distribution without a significant change in regurgitant volume in the tested comparison.
