Dobutamine stress echocardiography can predict reversible ventricular dysfunction after acute myocardial infarction.

Background: The aim of early treatment of acute myocardial infarction (AMI) is to achieve the rapid reperfusion of the culprit artery, which correlates with improvement in ventricular function and survival. With the widespread use of thrombolytic agents or coronary angioplasty as reperfusion strategies for AMI, it is possible to reduce the amount of myocardial necrosis.

Hypothesis: The assessment of residual viability with dobutamine stress echocardiography (DSE) in the infarcted area after AMI is relevant to subsequent management and prognosis.

Liposarcoma causing left ventricular outflow tract obstruction and syncope: a case report and review of the literature.

Metastatic cardiac myxoid liposarcoma is rare. We present the case of a 56-year-old woman who was admitted for angina and syncope, and in whom a mobile intracardiac mass obstructing the left ventricular outflow tract and protruding into the aortic root during systole was detected by transesophageal echocardiography (TEE). She reported an antecedent of the complete excision of a myxoid liposarcoma of the thigh 12 years before.
