Fig. 4From: Ex vivo biomechanical analysis of flexible versus rigid annuloplasty rings in mitral valves using a novel annular dilation systema Mean transmitral flow tracings confirmed mitral regurgitation after annular dilation. Rigid annuloplasty ring repair successfully eliminated mitral regurgitation. b, c Mean pressure tracings at baseline, post dilation, and after ring annuloplasty repair.
