Intraventricular gradients and acute coronary syndromes: a case report.
Left ventricular outflow tract obstruction (LVOTO) has traditionally been associated with hypertrophic obstructive cardiomyopathy, but can occur in other clinical scenarios such as acute myocardial infarction (AMI). In some patients, LVOTO is absent at rest, being detectable only with provocation tests such as stress echocardiography. Timely diagnosis of this phenomenon is very important, as it has therapeutic implications, and relies on clinical suspicion and on recognizing substrates in which LVOTO can occur. We report a case of syncope and AMI associated with LVOTO with systolic anterior motion of the mitral valve and a significant intraventricular gradient.
