Mitral Valve Repair for Mitral Valve Regurgitation with Papillary Muscle Displacement and Posterior Leaflet Prolapse
2017
A case of abnormal chordae of the mitral valve (MV) associated with systolic
anterior motion (SAM) is not commonly encountered in clinical practice.
Here we report MV repair via the edge-to-edge technique in a 56-year-old
male with MV regurgitation associated with papillary muscle displacement
and posterior leaflet prolapse. Echocardiography revealed obstruction of the
left ventricular outflow tract caused by SAM because of papillary muscle displacement
and mitral regurgitation associated with posterior leaflet prolapse
due to chordae rupture. MV repair was successfully performed by reconstruction
with an Alfieri stitch. The outcome of this case demonstrated that this
surgical technique is preferable for MV abnormalities with no complex malformations.
