From: An axis-specific mitral annuloplasty ring eliminates mitral regurgitation allowing mitral annular motion in an ovine model

Fig. 8

a Gross images revealed appropriate integration of the axis-specific ring within the native annulus characterized by complete device coverage by mature, endothelialized neoendocardium. Scale bar = 1 cm. At 3 (b) and 6 (c) months after ring implantation, the axis-specific rings were attached to the left atrium by neoendocardium. The aorto-mitral curtains and anterior mitral leaflets were connected to the undersurface of the axis-specific rings. At the lateral aspect, the native posterior mitral valve leaflets extended from the inferior edges of the novel rings at the left ventricular surface. Scale bars = 2 mm.
