Myocardial contrast echocardiography in coronary artery disease.
Myocardial contrast echocardiography (MCE) allows the assessment of myocardial perfusion by imaging the coronary microcirculation. The development of new contrast agents and new diagnostic tools far assessing myocardial perfusion by means of MCE has led to a new field of applications far patients suffering from ischemic heart disease. Several studies have shown that MCE is a feasible and accura...
متن کاملStress echo without the stress: detection of coronary stenosis at rest by myocardial contrast echocardiography.
Exercise or pharmacological stress has long been a mainstay of diagnostic testing aimed at identifying the presence of a flow-limiting coronary stenosis. The basis for this is the well-known clinical observation that even severe coronary artery atherosclerosis does not usually cause angina or ischemia at rest. Sir William Osler observed that angina pectoris is commonly precipitated by “muscular...
متن کاملDetection of myocardial ischaemia caused by coronary artery-left ventricular fistulae using myocardial contrast echocardiography.
A coronary artery-left ventricular fistula (CAF) is an extremely rare anatomical abnormality in which blood drains directly from a coronary artery into the left ventricle. CAF may cause myocardial ischaemia and angina. Myocardial contrast echocardiography (MCE) is a non-invasive technique which assesses myocardial perfusion. We describe a patient with CAF in whom transmural myocardial ischaemia...
متن کاملDetection of coronary stenosis with myocardial contrast echocardiography using regadenoson, a selective adenosine A2A receptor agonist.
AIMS Regadenoson is comparable to adenosine in pharmacologic radionuclide stress tests but has not been studied with stress myocardial contrast echocardiography. This study assessed the haemodynamic profile and ability of regadenoson, a novel selective A(2A) receptor agonist, to detect coronary artery stenosis during myocardial contrast echocardiography. METHODS AND RESULTS Myocardial contras...
متن کاملDetection of coronary stenoses at rest with myocardial contrast echocardiography.
BACKGROUND We hypothesized that autoregulatory changes in arteriolar blood volume (aBV) that develop distal to a stenosis can be measured with myocardial contrast echocardiography, allowing coronary stenosis detection at rest without recourse to stress. METHODS AND RESULTS Patients with varying degrees of coronary artery stenosis on quantitative angiography underwent high-mechanical-index myo...
