Figure 2: (a) Surgeon's view of the mitral valve demonstrating a thick supra-annular fibrous ring. The resection is completed using sharp and blunt dissection. (b) The subvalvar area is often exposed by incising the posterior leaflet. (c) and (d) Secondary tethering chords are then separated and/or divided to improve mobility of the posterior leaflet. (e) A pericardial patch is used to augment the posterior leaflet. (f) Lateral view after complete resection and mobilization
