Quantitative Assessment of Microcollateral Recruitment During Coronary Occlusion Using Real-time Intravenous Myocardial Contrast Echocardiography
2008, Journal of the American Society of EchocardiographyCitation Excerpt :Furthermore, anatomic and morphometric methods, such as postmortem casts, dyes, and colored or radiolabeled microspheres, have been used to identify coronary collateral microvascular anatomy; however, these assessments cannot be performed repetitively in short periods of time. We have already reported that the acute protective effects of coronary collaterals during acute coronary occlusion are significantly correlated with myocardial perfusion assessed using MCE, rather than the angiographic epicardial collateral vessel filling.4 Many studies have reported the advantages and superiority of MCE to coronary angiography.8,9
Myocardial contrast echocardiography assessment of acute changes in collateral perfusion of contralateral coronary artery with coronary flow reserve after coronary angioplasty
2005, Journal of the American Society of EchocardiographyIntraoperative ischemia and long-term events after minimally invasive coronary surgery
2004, Annals of Thoracic SurgeryCitation Excerpt :Another limitation is that troponin enzymes were not systematically available at the time of the study. Myocardial contrast echocardiography is more accurate than coronary angiography in the detection of collateral circulation [19] and could have added insights into the mechanism of protection against ischemia. Also, the metabolic effects of coronary occlusion were not assessed in the present study.
Fate of collateral circulation after successful coronary angioplasty of total occlusion assessed by coronary angiography and myocardial contrast echocardiography
2002, Journal of the American Society of EchocardiographyCitation Excerpt :Therefore, previous studies only assessed epicardial collateral vessel filling rather than myocardial perfusion through the collateral circulation in the occluded bed. MCE is a suitable imaging technique for the assessment of myocardial perfusion through collateral flow by the selective intracoronary injection of a sonicated contrast medium into a donor coronary artery.26-35 Previous studies have demonstrated the functional significance of collateral flow detection by MCE in both the experimental and clinical setting.
Acute changes in systolic and diastolic events during clinical coronary angioplasty: A comparison of regional velocity, strain rate, and strain measurement
2002, Journal of the American Society of EchocardiographyCitation Excerpt :The impact of collateral circulation on myocardial function and global left ventricular performance has already been well recognized.29,30 It has been also shown that collaterals protect “at-risk” areas during coronary angioplasty of the related artery.35 Thus, they can alter the response of a myocardial segment to acute ischemia.
