Acquired dynamic left ventricular outflow tract obstruction complicating acute anterior myocardial infarction: serial echocardiographic and clinical evaluation.
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.
