A trileaflet "mitral valve" with three papillary muscles: brand new echocardiographic finding.
Congenital mitral valve malformations are rare, but are well known and described entities. Mitral valve malformations involve mitral valve apparatuses (leaflets and annulus) and subvalvar apparatuses (chordae and papillary muscle). Case reports of accessory mitral leaflets were already described, but were usually an appendix of the normal valve. We describe here a case report and present the images of a trileaflet mitral valve sustained by three papillary muscles in a young girl with subaortic stenosis.
