Time-dependency of edema-based assessment of area-at-risk in reperfused acute myocardial infarction
Methods Cardiac MR was used to investigate the development and persistence of edema volume increases in the acute postinfarct period using both T2-weighted STIR imaging and T2 maps. LAD instrumented canines (n=9) underwent three hours of no-flow ischemia followed by reperfusion and were studied [using Siemens 1.5 T Espree scanner] at five time points (before and during ischemia and 2, 5, 7 and ...
متن کاملArea-at-risk determination by technetium-99m-hexakis-2-methoxyisobutyl isonitrile in experimental reperfused myocardial infarction.
In a canine model of reperfused myocardial infarction, we tested the hypothesis that after reperfusion, technetium-99m-hexakis-2-methoxyisobutyl isonitrile (Tc-MIBI) tomographic imaging still reflects occlusion blood flow when the tracer is injected before reperfusion. Nine anesthetized dogs underwent 2 hours of coronary occlusion followed by 3 hours of reperfusion ending by being killed. Refer...
متن کاملThe salvaged area at risk in reperfused acute myocardial infarction as visualized by cardiovascular magnetic resonance.
OBJECTIVES We aimed to characterize the tissue changes within the perfusion bed of infarct-related vessels in patients with acutely reperfused myocardial infarction (MI) using cardiovascular magnetic resonance (CMR). BACKGROUND Even in successful early revascularization, intermittent coronary artery occlusion affects the entire perfusion bed, also referred to as the area at risk. The extent o...
متن کاملIntramyocardial hemorrhage in spontaneously reperfused myocardial infarction.
OBJECTIVE. The presence of intramyocardial hemorrhage (IMH) is frequent in patients with acute myocardial infarction (AMI) undergoing primary percutaneous coronary intervention (PPCI). We aim for the presence IMH using cMRI in patients who presented AMI and did not undergo PPCI or thrombolysis. Cardiac magnetic resonance has proven to be a highly sensitive method for detect its presence in the ...
متن کاملDetermination of the myocardial area at risk after reperfused acute myocardial infarction with different imaging techniques: cardiac magnetic resonance imaging, multidetector computed tomography and histopathological validation
Purpose The principal objective of this study was to compare the AAR defined with two different T2 weighted cardiac magnetic resonance (T2W CMR) imaging sequences (TIRM T2w blood suppressed TSE and ACUTE TSESSFP), the contrast-enhanced (ce-) CMR endocardial surface length (ESL) after 90-minutes of reperfusion and the arterial enhanced multi-detector computed tomography (MDCT) performed during o...
