(A) Basal short axis fast-SENC peak systolic image in a 53 year old healthy female subject demonstrating normal longitudinal shortening (E_LL) (red color). (B) Basal short axis fast-SENC peak systolic image in a 47 year old female PH patient (mPAP = 51 mmHg). Note regionally reduced RV E_LL and LV antero-septal E_LL (white color). Probe points correspond to regions of interest where strain was measured. A mesh was used to measure LV E_LL at six basal, six mid and four apical LV segments respectively.
