Mini‐Abstract Although isolated systolic anterior motion ( SAM ) of the posterior mitral valve leaflet has been previously documented in hypertrophic cardiomyopathy, this case highlights the therapeutic implications of diagnosing this phenomenon and the importance of meticulous echocardiographic techniques in these patients. We present a case of SAM of the posterior leaflet producing persistent dynamic left ventricular outflow tract obstruction despite septal myectomy and subsequent revision myomectomy in a patient with hypertrophic cardiomyopathy.
