Posterior mitral leaflet plication may be a viable surgical option to correct residual systolic anterior motion in hypertrophic obstructive cardiomyopathy, potentially avoiding the need for mitral valve replacement.
Posterior mitral leaflet plication may resolve residual SAM after anterior plication and myectomy; hypothesis-generating case report requiring prospective validation.
Anomalies of the mitral valve apparatus in hypertrophic cardiomyopathy are an important cause of systolic anterior motion. Patients with significant residual obstruction due to systolic anterior motion after myectomy and anterior mitral leaflet plication may end up having mitral valve replacement. We describe the case of a 52-year-old man who underwent posterior mitral leaflet plication to correct residual systolic anterior motion after anterior mitral leaflet plication.
