Inter- and intraobserver consistency in LV myocardial strain measurement using a novel multi-layer technique in patients with severe aortic stenosis and preserved LV ejection fraction
Inter and intraobserver TTE reproducibility for 2D LV GLS and GCS were measured. Severe AS subjects with preserved LVEF underwent multi-layer strain TTE. Inter- and intra-observer reproducibility were better for 2D LV GLS than GCS.
