The effect of time and of vasoactive drugs on capillary leakage induced during myocardial contrast echocardiography.
BACKGROUND Premature ventricular contractions (PVC), capillary leakage, and petechial hemorrhage can occur during myocardial contrast echocardiography (MCE). The effects occur as a result of the interaction of contrast agent microbubbles and the ultrasound, but the detailed etiology of the effects is not yet clear. This study tested the hypothesis that the capillary leakage results from a physi...
متن کاملTransient myocardial ischemia during acetylcholine-induced coronary microvascular dysfunction documented by myocardial contrast echocardiography.
A 77-year-old white woman was referred for diagnostic coronary angiography after a 6-month history of exertional breathlessness and back pain. Her cardiovascular risk factors were hypercholesterolemia (low-density lipoprotein, 153 mg/dL) and a positive family history for cardiovascular disease (father died at 73 years of age because of a peripheral artery occlusive disease event). Furthermore, ...
متن کاملHistological characterization of microlesions induced by myocardial contrast echocardiography.
BACKGROUND Myocardial contrast echocardiography (MCE) has been shown to have a potential for apparently reversible side effects related to the interaction of ultrasound with the contrast microbubbles, including premature ventricular contractions and microvascular leakage. We investigated the potential for high-dose MCE to induce histologically definable microlesions. METHODS Myocardial contra...
متن کاملEvaluation of dynamic changes in microvascular flow during ischemia-reperfusion by myocardial contrast echocardiography.
BACKGROUND Dynamic changes of myocardial blood flow have been observed after reperfusion of an occluded coronary artery. MCE performed by intracoronary contrast injection can provide an estimate of microvascular flow. We hypothesized that MCE performed using intravenous infusion of a new generation contrast agent and electrocardiogram-gated harmonic imaging would be able to assess serial change...
متن کاملMyocardial contrast echocardiography.
MCE has evolved from a laboratory tool to a clinical procedure. It would be wrong to consider it merely another tool for imaging of myocardial perfusion. As discussed, it allows physicians to bring physiology and pathophysiology to the bedside, providing a better understanding of the underlying mechanisms of abnormal findings in individual patients. MCE can provide quantitative measurements tha...
