Histopathological and immunohistochemical characteristics of chordae tendineae affected by degenerative processes in canine myxomatous mitral valve disease.

Summary: Imagine your dog's heart has tiny "strings" that help pump blood in the right direction. In a common heart condition called mitral valve disease, these strings can wear out and even snap! Scientists looked closely at these strings under a microscope to see exactly what goes wrong. They found that the building blocks making up the strings, like collagen and other proteins, change and break down as the disease gets worse. Understanding this microscopic damage could help us find better ways to protect our furry best friends' hearts from failing in the future.
