Abstract

In patients with functional/ischemic mitral regurgitation (FMR/IMR), mitral annuloplasty alone frequently results in recurrent regurgitation because of ongoing left ventricular dilatation and recurrent leaflet tethering. Adjunctive subvalvular approaches exist, but the technical shortcomings limit their clinical acceptance. A novel adjunctive technique was applied in three patients: A polytetrafluoroethylene string and noose were anchored to the posteromedial and anterolateral papillary muscle, respectively. The string ends were guided through the noose, exteriorized through the midposterior annulus into the left atrium, and length-adjusted during the saline test. The procedure allowed safe and straightforward papillary muscle repositioning and may stabilize repair results in FMR/IMR patients.
