Acute myocardial ischemia resulting in dynamic obstruction to the left ventricular outflow relieved by successful angioplasty.

A patient was admitted because of an acute myocardial infarction which evolved with heart failure and postinfarction angina. A pattern consistent with dynamic left ventricular outflow obstruction was found. It disappeared after coronary angioplasty was performed on the vessel responsible for the ischemia.
