“…Various technical modifi cations⎯e.g., sliding plasty, 8,14-16 folding, 1,2,17,18 double-breasted repair, 19 longitudinal plication of the posteromedial ligament (PML), 20,21 anterior leafl et reduction, 22,23 edge-to-edge repair, 24 careful ring selection⎯might aid in reducing the incidence of postrepair SAM associated with valverelated causes. 25 A previous report even described septal myectomy as an effective alternative to resolve postrepair SAM, the cause of which might be related to a ventricular septal abnormality.…”

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.

“…One of the simplest techniques used for this purpose is the Alfieri's edge-to-edge suture [7]. It seems not to compromise durability when used to avoid SAM after a satisfactory repair, as opposed to its use to correct MR after inadequate repair [8].…”

Systolic anterior motion of the mitral valve is a feared complication after valve repair, with important implications in the postoperative period. Provocation with isoproterenol is valuable in the assessment of its mechanism and severity in high-risk patients. Surgical correction of this condition is sometimes difficult and may require valve replacement. We present a modification of Alfieri's edge-to-edge technique that adapts better to the mechanism of systolic anterior motion (SAM) after mitral repair in selected patients by placing the edge-to-edge suture between the A1-P1 segments and not in the midline.
