Segmental strain analysis by deformation of a mesh model: comparison of segmental strain metrics and late gadolinium enhancement quantification in myocardial infarction
نویسندگان
چکیده
Background The presence and transmurality of posterolateral scar within the left ventricle by late gadolinium enhancement (LGE) imaging has been shown to portend poor response to cardiac resynchronization therapy due to placement of the LV lead in this region. Unfortunately, the use of gadolinium is contraindicated in patients with significant renal dysfunction due to the risk of nephrogenic systemic fibrosis. Alternative measures of regional myocardial non-viability by 4D strain analysis may be highly useful for CRT evaluation in patients with heart failure and renal dysfunction.

Predictive value of segmental extent of late gadolinium enhancement and peak circumferential systolic strain in predicting improvement and normalisation of dysfunctional segments post STEMI
Background Segmental infarct transmurality on late gadolinium enhancement (LGE) acutely post ST-elevation myocardial infarction (STEMI) has been shown to predict segmental function in a few small studies. The predictive power of segmental area of enhancement (n=45) and myocardial salvage (n=34) have been analysed in one small study each. Feature Tracking (FT) quantifies strain on routinely acqu...

AIMS Separate analysis of endocardial and epicardial myocardial layer deformation has become possible using strain-encoded cardiovascular magnetic resonance (SENC) and 2D-dimensional speckle tracking echocardiography (Echo). This study evaluated and compared both modalities for the assessment of infarct transmurality as defined by late gadolinium enhancement (LGE) cardiovascular magnetic resona...

BACKGROUND Quantification of late gadolinium enhanced cardiovascular magnetic resonance (LGE CMR) by objective window setting increases reproducibility and facilitates multicenter comparison and cooperation. So far, quantification methods or models have only been validated to postmortem animal studies. This study was undertaken to evaluate quantification of LGE in relation to the clinical stand...
متن کاملFeature tracking derived longitudinal and circumferential myocardial strain abnormalities in clinical myocarditis
Background Cardiac magnetic resonance imaging (CMR) is frequently used to assess myocardial involvement to confirm diagnosis of myocarditis. CMR techniques employ T2weighted, early and late gadolinium enhancement (LGE), with two positive sequences widely considered diagnostic for myocardial inflammation. However, these techniques are qualitative and subjective, thus prone to interpretation erro...
متن کاملClinical assessment of left ventricular rotation and strain: a novel approach for quantification of function in infarcted myocardium and its border zones.
Left ventricular (LV) circumferential strain and rotation have been introduced as clinical markers of myocardial function. This study investigates how regional LV apical rotation and strain can be used in combination to assess function in the infarcted ventricle. In healthy subjects (n = 15) and patients with myocardial infarction (n = 23), LV apical segmental rotation and strain were measured ...
