Key result
Post-repair systolic anterior motion of the mitral valve developed despite preventive surgical techniques and was successfully eliminated using a surgical edge-to-edge (Alfieri) repair.
Case Report (n=1)
In a patient at high risk for post-repair SAM, preventive surgical techniques failed, but the complication was successfully managed with an edge-to-edge (Alfieri) repair.
Edge-to-edge repair may resolve refractory post-MV repair SAM; hypothesis-generating and should not yet change practice.
A patient with myxomatous mitral valve prolapse underwent mitral mitral valve repair due to severe symptomatic mitral regurgitation. Preoperative echocardiography demonstrated systolic anterior motion of the mitral valve. This finding disappeared once spontaneous chordal rupture occurred, resulting in a flail posterior mitral leaflet. As the patient was considered at high risk of developing post-repair SAM, he was operated on using surgical techniques aimed at lowering the risk of this complication. Despite this, post-repair SAM did develop and could only be eliminated by a surgical edge-to-edge (Alfieri) repair.

Eyal et al. (2013) conducted a case report in Myxomatous mitral valve prolapse with severe symptomatic mitral regurgitation (n=1). Mitral valve repair including surgical edge-to-edge (Alfieri) repair was evaluated on Elimination of post-repair systolic anterior motion (SAM). Post-repair systolic anterior motion of the mitral valve developed despite preventive surgical techniques and was successfully eliminated using a surgical edge-to-edge (Alfieri) repair.
