New Myocardial Deformation by 2D Multi-layer Speckle-Tracking Analysis in Healthy Patients: Normal Reference Values and Their Physiologic Determinants
There are limited data regarding intrinsic changes of the left (LV) and right ventricular (RV) deformation assessed layer-by-layer. We designed a prospective multi-centric study, using a new multi-layer 2D-speckle-tracking-echo (MSTE). We investigated the impact of different physiologic parameters o...

Zusammenfassung: | There are limited data regarding intrinsic changes of the left (LV) and right ventricular (RV) deformation assessed layer-by-layer. We designed a prospective multi-centric study, using a new multi-layer 2D-speckle-tracking-echo (MSTE). We investigated the impact of different physiologic parameters on layer-specific LV/RV myocardial deformation and synchrony, in a large group of healty subjects. 151 subjects were feasible for MSTE, divided in 4 groups: 61 yrs. We found a significant higher LV dyssynchrony index with age. In all groups, an endo-epicardial gradient was present in longitudinal LV/RV and circumferential deformation, with higher values in endocardial layer (p |
