title: Myectomy as an alternative solution for systolic anterior motion in a patient who underwent mitral valve repair.
abstract: Systolic anterior motion (SAM) of the mitral apparatus is a relatively frequent complication of mitral valve repair. When significant SAM persists despite intraoperative medical therapies, a second repair is generally required. We describe a rare case of SAM due to a hypertrophic septum in a patient who underwent mitral valve repair, with no preoperative obstruction of the left ventricular outflow tract. The present case of SAM was successfully treated only with transaortic septal myectomy. Therefore, myectomy might be considered as an alternative solution for SAM that is suspected to be caused by a hypertrophic septum after mitral valve repair.
