LV, LA, RV, RA

Myocardial mechanics — the left ventricle

LV systole / diastole

Ejection fraction — How, Why, Biplane (Simpson) / 2D Strain (longitudinal)

Indications for Strain Imaging

Quality criteria Strain Imaging / Speckle Tracking Echocardiography

Normal values of Strain Imaging — LV Strain

17-Segment Model for Bulls-eye

How to measure LV Strain

Normal LV Strain — Bulls-eye

Region of Interest (ROI)

Angle & Foreshortening

PSI & Dispersion

Normal values – RV strain

Normal values – LA strain

Normal values – RA strain

Limitations of Strain Imaging

Angle vs Foreshortening

Optimal measurement in the focused 4-ChV vs foreshortening

Optimal measurement in the focused 4-ChV vs foreshortening

Subcostal limitation in strain measurement
due to subopitmal angle and foreshortening

Subcostal limitation in strain measurement
due to subopitmal angle and foreshortening

Foreshortening should be avoided
as it changes the strain measurement (overestimation)
