Impact of the MitraClip Procedure on Left Atrial Strain and Strain Rate

strain evaluation of left atrial function: ready for the future?

assessment of left atrial function after percutaneous coronary intervention: a doppler-based strain and strain rate study

conclusions pci was accompanied by some improvement in left atrial deformation indices as assessed by tissue doppler imaging. revascularization can, therefore, improve patient outcome. results regarding changes in left trial functional parameters after pci, those such as the strain of the septal wall and the anterior and inferior walls and the strain rate of the anterior and lateral walls signi...

Do left atrial strain and strain rate reflect intrinsic atrial function, or are they determined by left ventricular function?

BACKGROUND Left atrial (LA) strain (S) and strain rate (SR) are reported as measures of intrinsic function. AIM Since the LA and left ventricle (LV) are connected through the mitral annulus, we investigated: (1) if deformation indices in the LA are mostly predicted by deformation of the LV; (2) if timings of S and SR events are similar in both the LA and LV; and (3) if alteration of S and SR ...

Quantification of left atrial strain and strain rate using cardiovascular magnetic resonance myocardial feature tracking

Background Cardiovascular Magnetic Resonance myocardial feature tracking (CMR-FT) is a quantitative technique tracking tissue voxel motion on standard steady-state free precession (SSFP) cine images to assess ventricular myocardial deformation. The importance of left atrial (LA) deformation assessment is increasingly recognized and can be assessed with echocardiographic speckle tracking. Howeve...

Reply: A comprehensive evaluation of left atrial performance using volumetric analysis, strain, and strain rate imaging.

into the pathogenesis of heart disease in patients treated for HIV infection. Lipodystrophy can indeed lead to ectopic spillover of triglyceride into nonadipose tissues—including the myocardium—and has previously been associated with adverse LV remodeling (2). Furthermore, that HAART exposure also predicted myocardial triglyceride content and LV dysfunction provides further insight into the pat...
