Dynamic left ventricular outflow tract (LVOT) and mid-cavitary obstruction has been associated with hypertrophic obstructive cardiornyopathy. . Acute LVOT and mid - cavitaryobstruction has been described as a complication of myocardial infarction (MI). In the latter situation, this unusual form of dynamic obstruction occurs as a result of compensated hyperdynamic basal wall motion in patients with apical infarction. We describe a patient who developed mid-cavitary obstruction following silent anteroseptal MI.
