recommendations. A new section on the use of intraoperative transesophageal
echocardiography (TEE) is being added to update the guidelines published by the American …

2 Methods The available studies were identified by MEDLINE searches using the following
key words: noninvasive imaging, stress echocardiography, dobutamine, dipyridamole …

Objectives. This study evaluated the relative merits of the most frequently used techniques
for predicting improvement in regional contractile function after coronary revascularization in …

Objectives: This study examined the effect of aspirin on the risk of embolic events in infective
endocarditis (IE). Background: Embolism is a major complication of IE, and studies in animal …

Methods A MEDLINE search (1980 through January 2000) was performed using the search
term “myocardial viability” in combination with a set of terms for the techniques:“Thallium …

We investigated early and late effects of percutaneous revascularization for chronic total
coronary occlusion on left ventricular (LV) function and volumes. Magnetic resonance …

Background Recovery of function is possible in patients with ischemic cardiomyopathy when
left ventricular dysfunction is caused by stunning or hibernation. It is plausible that recovery …

Observations of reversibility of cardiac contractile dysfunction in patients with coronary artery
disease and ischemia were first made more than 40 years ago. Since that time a wealth of …

OBJECTIVES.: We sought to directly compare the diagnostic value of exercise-redistribution-
reinjection thallium single-photon emission computed tomography (SPECT) and low dose …

Background—Both radionuclide perfusion tracers and contractile response to dobutamine
have been used to identify hibernating myocardium. The aim was to compare 201Tl …
