Abstract
The surgical treatment of chronic ischemic mitral regurgitation remains a challenging issue. Several procedures have been developed to correct displacement of the papillary-ventricular complex and to reduce tethering-induced regurgitation. We report a geometric approach to relocate the laterally displaced posterior papillary muscle towards the mitral annulus. This procedure is believed to be technically easy and useful, especially in cases in which the displaced posterior papillary muscle contributes to tethering-induced regurgitation.
