Viability assessment by delayed enhancement cardiovascular magnetic resonance: will low-dose dobutamine dull the shine?
Since mechanical revascularization methods such as coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention became available, the issue of identifying dysfunctional yet viable myocardium has been of crucial clinical importance. Among patients with ischemic cardiomyopathy and viable myocardium, mechanical revascularization is associated with improved systolic function, ...
متن کاملAssessment of myocardial viability by cardiovascular magnetic resonance.
Patients with ischemic heart disease may have left ventricular (LV) dysfunction due to reversible or irreversible causes. The ability to distinguish viable myocardium with dysfunction due to a reversible etiology (hibernation, stunning) from nonviable scar is critical for determining proper management of the patient. Cardiovascular magnetic resonance (CMR) is a technique that has been establish...
متن کاملValue of Delayed-Enhancement Cardiovascular Magnetic Resonance Imaging in Predicting Myocardial Viability After Surgical Revascularization
Background—Despite the accepted utility of delayed-enhancement MRI in identifying irreversible myocardial injury, no study has yet assessed its role as a viability tool exclusively in the setting of coronary artery bypass surgery (CABG), and no study has repeated delayed-enhancement MRI late after revascularization. In a clinical trial in which patients underwent CABG by either the off-pump or ...
متن کاملDelayed-Enhancement Cardiovascular Magnetic Resonance Coronary Artery Wall Imaging
Results A greater prevalence of strong DE was noted with greater MSCT evidence of disease, with DE in 2 (7%) of 30 coronary segments with no plaque by MSCT, in 1 (10%) of 10 segments with noncalcified plaque on MSCT, and in 16 (36%) of 44 segments with calcifications by MSCT (p 0.009, adjusted p 0.035). Delayed enhancement was observed in 8 (53%) of 15 segments with 20% coronary artery stenosis...
متن کاملRapid detection of myocardial infarction by subsecond, free-breathing delayed contrast-enhancement cardiovascular magnetic resonance.
BACKGROUND An ultrafast, delayed contrast-enhancement cardiovascular magnetic resonance technique that can acquire subsecond, "snapshot" images during free breathing (subsecond) is becoming widely available. This technique provides myocardial infarction (MI) imaging with complete left ventricular coverage in < 30 seconds. However, the accuracy of this technique is unknown. METHODS AND RESULTS...
