Significats de circumferential strain en anglès

Feature tracking was only accurate for quantification of mid LV circumferential strain.

Conclusions: Patients with acute perimyocarditis have lower twist angle, longitudinal and circumferential strain.

LV radial and circumferential strain and strain rate, apical and basal rotation, and LV torsion were recorded.

The enhanced LV circumferential strain might be the mechanism of compensation to maintain the normal LVEF in these patients.

Multivariable regression analysis suggests that preserved LV twist and circumferential strain may contribute to normal EF in patients with DHF.

Peak twist, circumferential strain, and radial strain were compared between acquisitions employing different ke using Bland-Altman analyses and coefficients of variation.

Green-Lagrange circumferential strain analysis revealed higher strain values proximal and distal to the aneurysm than within the aneurysmal region, consistent with published reports.

The time delay between septal and lateral LV wall peak circumferential strain (septal-to-lateral wall delay) was measured by cardiac magnetic resonance.

Systolic radial strain and strain rate peak values showed little variability compared with systolic circumferential strain and strain rate and to all diastolic measurements.

Global area strain (GAS) was calculated by 3DSTE as percentage of variation in surface area defined by the longitudinal and circumferential strain vectors.

Echocardiographic parameters including LVEF, and global peak longitudinal and circumferential strains were measured.

Radial and circumferential strains from those segments were significantly correlated with the readout duration.
