Impact of apical foreshortening on deformation measurements: a report from the EACVI-ASE Strain Standardization Task Force

Abstract

Optimal image geometry is crucial for accurate LV function assessment. Foreshorhening of apical views has a substantial impact on longitudinal strain measurements, predominantly in the apex and in the endocardial layer. Our data suggest that measuring midwall strain might therefore be the more robust approach for clinical routine use.
