Myocardial perfusion by contrast echocardiography. Establishment of normal pattern of intracoronary injection and safety in humans.
OBJECTIVE To establish the normal pattern and safety of echocardiographic contrast in patients with no significant obstruction of epicardial coronary arteries. METHODS 67 patients with normal coronary arteries or obstructions < 50% were selected from 277 patients who underwent coronary angiography (CA). Mean age was 56 +/- 11 years and 36 were males. At the end CA, echocardiographic contrast ...
متن کاملChanges in transmural distribution of myocardial perfusion assessed by quantitative intravenous myocardial contrast echocardiography in humans.
OBJECTIVE To clarify whether changes in transmural distribution of myocardial perfusion under significant coronary artery stenosis can be assessed by quantitative intravenous myocardial contrast echocardiography (MCE) in humans. METHODS 31 patients underwent dipyridamole stress MCE and quantitative coronary angiography. Intravenous MCE was performed by continuous infusion of Levovist. Images ...
متن کاملThe behavior of sonicated albumin microbubbles within the microcirculation: a basis for their use during myocardial contrast echocardiography.
The purpose of this study was to determine whether the behavior of sonicated albumin microbubbles accurately mimics red blood cell flow in the microcirculation and is thus consistent with their use as in vivo tracers of red blood cell flow during myocardial contrast echocardiography. Accordingly, microbubbles prepared from fluorescein-conjugated albumin and fluorescently labeled red blood cells...

متن کاملMyocardial perfusion imaging: contrast echocardiography today and tomorrow.
The clinical need to evaluate myocardial perfusion is not satisfied by conventional imaging techniques (I). Angiography is frequently used to provide qualitative anatomic data, but it lacks a physiologic basis for assessing regional blood flow and is an unreliable predictor of it (2,3). Recent technical advances in contrast echocardiography permit direct perfusion assessment and promise to prov...
