Segmental strain analysis by deformation of a mesh model: comparison of segmental strain metrics and late gadolinium enhancement quantification in myocardial infarction
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 sy...
متن کاملReperfused myocardial infarction in mice: 3D mapping of late gadolinium enhancement and strain.
We developed mathematical modeling tools for mapping 3D infarct geometry from multislice late gadolinium enhancement data, allowing fusion with multislice MR tagging data, in mice with myocardial infarction. Five C57BL/6 mice were imaged at baseline, 1, 7 and 28 days after 60 min occlusion of the left anterior descending coronary artery. The 3D infarct geometry was mapped in material coordinate...
متن کاملValue of segmental myocardial strain by 2-dimensional strain echocardiography for assessment of scar area induced in a rat model of myocardial infarction
OBJECTIVES Two-dimensional strain echocardiography (2DSE) technique has enabled accurate quantification of regional myocardial function. This experimental study was aimed to investigate the value of 2DSE in detection of segmental regional myocardial dysfunction induced by fibrosis following myocardial infarction in a small animal (rat) model. METHODS A rat model of myocardial infarction was e...
متن کاملSegmental late gadolinium enhancement and gadolinium extracellular volume in hypertrophic cardiomyopathy
Background Late gadolinium enhancement (LGE) by cardiac magnetic resonance (CMR) is a common finding in patients with hypertrophic cardiomyopathy (HCM), and its extent correlates with clinical parameters such as ventricular tachycardia and sudden cardiac death. While LGE has been shown to reflect focal replacement fibrosis, recently optimized T1 mapping techniques have allowed for the quantific...
متن کاملQuantification of Regional Myocardial Function following Acute Myocardial Infarction by Ultrasonic Strain Rate and Strain Imaging
Objectives: The rapid diagnosis and early risk stratification of patients presenting with acute myocardial infarction (AMI) is important. In experimental setting ultrasonic strain rate (SR) and strain (S) have been shown to identify changes in deformation predictive of ischemia. We sought to evaluate and compare regional myocardial function at “the risk zone” (ARZ) supplied by the culprit coron...
