Myocardial extracellular volume estimation by CMR predicts functional recovery following acute myocardial infarction
نویسندگان
چکیده
Background The transmural extent of myocardial infarction (MI) as assessed by late gadolinium enhancement (LGE) CMR predicts functional recovery. In acute MI (AMI), myocardial edema and effects of reperfusion therapy reduce the predictive accuracy of LGE. LGE assesses tissue dichotomously as “viable” or “non-viable”, but does not consider the severity of tissue damage within the hyperenhanced infarct zone. Extracellular volume (ECV) estimation, using native and post-contrast T1 mapping CMR, allows for quantitative assessment of severity of myocardial damage. We aimed to assess if CMR-derived measurement of infarct ECV offers additional predictive value over LGE extent for contractile recovery in reperfused AMI.

Myocardial Extracellular Volume Estimation by CMR Predicts Functional Recovery Following Acute MI
OBJECTIVES In the setting of reperfused acute myocardial infarction (AMI), the authors sought to compare prediction of contractile recovery by infarct extracellular volume (ECV), as measured by T1-mapping cardiac magnetic resonance (CMR), with late gadolinium enhancement (LGE) transmural extent. BACKGROUND The transmural extent of myocardial infarction as assessed by LGE CMR is a strong predi...

Background Left ventricular wall motion assessment following acute myocardial infarction (AMI) allows prediction of functional recovery. Current methods are based upon visual assessment, with inherent operator variability. CMR myocardial feature tracking (CMR-FT) is a recently introduced technique for tissue voxel motion tracking on standard steady-state free precession (SSFP) images to derive ...

متن کاملRecovery of regional myocardial function and myocardial oedema following reperfused acute myocardial infarction
We investigated the relationship between myocardial oedema and recovery of regional myocardial function in patients with acute reperfused myocardial infarction (MI). Early after acute MI, oedema in the peri-infarct zone, as delineated by T2 weighted (T2w) cardiovascular magnetic resonance (CMR) imaging, demonstrated significantly reduced strain as compared to remote myocardium. The recovery of ...
متن کاملTime elapsed after contrast injection is crucial to determine infarct transmurality and myocardial functional recovery after an acute myocardial infarction
BACKGROUND In acute myocardial infarction (MI), late Gadolinium enhancement (LGE) has been proposed to include the infarcted myocardium and area at risk. However, little information is available on the optimal timing after contrast injection to differentiate these 2 areas. Our aim was to determine in acute and chronic MI whether imaging time after contrast injection influences the LGE size that...
