Abstract
Functional mitral regurgitation FMR is a common complication in patients with ischemic heart disease or idiopathic dilated cardiomyopathy DCM We report successful application of a papillary muscle sling PMS to maintain the efficacy of undersized mitral annuloplasty MAP in two patients with FMR A 5mm expanded polytetrafluoroethylene tube was placed around the trabecular base of the papillary muscles and then tightened to make a sling that banded the two papillary muscles together In case 1 a 57yearold woman who had experienced anterolateral myocardial infarction underwent mitral valve reconstruction with undersized MAP and PMS in addititon to coronary revascularization for chronic ischemic mitral regurgitation In case 2 we applied the same mitral valve procedure in a 65yearold woman with idiopathic DCM Neither had mitral insufficiency at an intermediate followup
