title: Acquired dynamic left ventricular outflow tract obstruction complicating acute anterior myocardial infarction: serial echocardiographic and clinical evaluation.
abstract: We describe three cases of dynamic outflow obstruction complicating acute anterior myocardial infarction. Serial echocardiography suggests the intraventricular gradient results from basal hyperkinesis, the latter being a reciprocal response to the apical wall motion abnormality.
