Symmetrical papillary muscle approximation for functional mitral regurgitation with idiopathic dilated cardiomyopathy.
The cases are reported of mitral valve repair with symmetrical papillary muscle approximation from heads to bases close to cardiac apex for functional mitral regurgitation (FMR). The two papillary heads attaching the chordae to both leaflets from the posteromedial papillary muscle were approximated parallel to the solitary head of the anterolateral papillary muscle. This procedure permits an even reduction of lateral shift of the papillary muscle, resulting in an elimination of mitral tethering, and provides a satisfactory and durable mitral valve repair with good outcomes in patients with idiopathic dilated cardiomyopathy and FMR.
