Myxomatous degeneration is a process of the fibrous layer of an AV valve breaking down to cause mitral valve prolapse (hooding) and the spongiform layer proliferating to cause nodular thickening of the cardiac valve leaflets, most severely at their tips. Myxomatous degeneration commonly affects the mitral and tricuspid valves in dogs. Chordae tendineae are also affected by the degenerative process, making them prone to rupture. The exact cause is unknown, but in Cavalier King Charles Spaniels and Dachshunds it is an inherited trait.
