title: Dynamic left ventricular outflow obstruction: a reversible mechanical complication of acute myocardial infarction.
abstract: Dynamic left ventricular outflow obstruction is a less well-known mechanical complication of acute myocardial infarction. Early diagnosis is important because initiation of proper management and avoidance of precipitating factors can lead to complete recovery. A patient is described who presented with acute myocardial infarction and in whom significant left ventricular outflow tract obstruction developed. Adequate therapy with beta blockers and calcium channel blockers led to complete resolution of the obstruction.
