Assessment of subendocardial function with myocardial contrast echocardiography.
The classical ischemic cascade anticipates perfusion disturbances to precede the development of wall motion abnormalities, but does not account for regional heterogeneity of both perfusion and function. In this issue of JACC: Cardiovascular Imaging, Xie et al. (1) examine the impact of subendocardial ischemia (identified using real-time myocardial contrast echocardiography [MCE]) on myocardial ...

متن کاملVisualization of subendocardial myocardial ischemia with myocardial contrast echocardiography in humans.
Previous studies indicate the degree of myocardial echo contrast enhancement may be related to regional myocardial perfusion. In this study, myocardial contrast echocardiography was used to characterize changes in the transmural myocardial blood flow distribution that were provoked by rapid atrial pacing in 11 patients with one-vessel coronary artery disease. Ten patients without coronary arter...
متن کاملAssessment of transmural distribution of myocardial perfusion with contrast echocardiography.
BACKGROUND We hypothesized that by using our newly defined method of destroying microbubbles and measuring their rate of tissue replenishment, we could assess the transmural distribution of myocardial perfusion. METHODS AND RESULTS We studied 12 dogs before and after creation of left anterior descending coronary artery stenoses both at rest and during hyperemia (n=62 stages). Microbubbles wer...
متن کاملAssessment of Myocardial Collateral Blood Flow with Contrast Echocardiography
Humans have pre-formed collateral vessels that enlarge with ischemia. In addition, new vessels can be formed within ischemic zones from pre-formed endocardial arcades of vessels providing rich collateral flow. Collateral flow under resting conditions (if >25% of normal) is enough to maintain myocardial viability, but may be insufficient to prevent myocardial ischemia under stress. Coronary angi...
