Systolic anterior motion (SAM) can be caused by multifactorial mechanisms, including structural, morphological and functional factors. We report an unusual case of a 76-year-old woman presenting with SAM associated with constrictive pericarditis. Echocardiography showed no septal hypertrophy but SAM and left ventricular outflow tract obstruction and moderate mitral regurgitation. The restoration of diastolic function after complete pericardiectomy successfully eliminated it.
