Fig. 1.
Pre- and post-repair regional mitral valve tethering patterns plotted against the distance travelled between the anterior commissure (AC) and posterior commissure (PC), (a, b) Regional mitral valve tethering area (MVTa) distribution pre- and post-repair. (c, d) Regional anterior tethering angle (ATA) distribution pre- and post-repair. (e, f) Regional posterior tethering angle (PTA) distribution pre- and post-repair. MVTa, ATA and PTA are plotted as a function of intercommissural distance, expressed as a percentage of the distance traveled from the AC. The positions of the AC and PC are 0 and 100%, respectively. NR = non-recurrrent; R = recurrent
