Papillary muscle approximation for functional ischemic mitral regurgitation.
In patients with ischemic left ventricular dysfunction and functional mitral regurgitation, surgical treatment of mitral insufficiency remains a challenging issue. Several procedures have been described to restore a near to natural alignment between the mitral annulus and the laterally displaced papillary muscles. We report a new approach to relocate the displaced papillary muscles toward the mitral annulus and to reduce tethering in 8 patients, providing satisfactory initial results. Echocardiography showed mild or no mitral regurgitation at the follow-up (mean, 11.4 +/- 3.6 months; range = 7 to 14 months). This procedure is believed to be technically easy and beneficial in terms of mitral repair.
