    Wang and Zhou's review links embryologic mechanisms to three major mitral valve phenotypes: rheumatic stenosis, congenital stenosis, and myxomatous prolapse.

  • 2

    The authors discuss endothelial injury, inflammatory pathways, and genetic predisposition as mechanisms for mitral valve disease onset and progression.

  • 3

    Mitral valve abnormalities in genetic syndromes highlight the relationship between developmental signaling and valve phenotype.

  • 4

    Updated data indicate that mitral valve involvement in RASopathies is significant, with regurgitant lesions being more common than stenotic ones.

  • 5

    The review emphasizes that syndromic conditions provide insights into the diverse genetic and developmental mechanisms influencing mitral valve pathology.
