Histological analysis of myxoid degeneration. a: analysis of myxomatous degeneration percentage (% MD) in groups 1 and 2. b: Normal valve. c: Mitral valve with MVD. The valve with myxomatous degeneration shows diffuse and homogeneous thickening, distorted architecture, spongy layer expansion and proteoglycan accumulation, indicated by the bluish Movat staining (a: atrial layer, b: spongy layer, and c: fibrous layer).
