Assessment of SRV Systolic Function

(A) 2-dimensional echocardiographic apical 4-chamber view. (B) 2-dimensional echocardiographic speckle tracking longitudinal strain showing severely reduced global strain partially contributed to by the stretched septal segments (dark blue and red curves). (C) 2-dimensional echocardiographic speckle tracking circumferential strain demonstrating a dominant contribution of the anterior and anterolateral segments (light blue, yellow, and red curves) and abnormal septal motion (purple curve). (D) Cardiac magnetic resonance demonstrating limited areas of fibrosis (arrows). (E) 3-dimensional echocardiographic volumetric analysis. (F) The ReVISION method analysis (Argus Cognitive, Lebanon, New Hampshire). AEF = anteroposterior ejection fraction; EDV = end-diastolic volume; EF = ejection fraction; ESV = end-systolic volume; FAC = fractional area change; GCS = global circumferential strain; GLS = global longitudinal strain; LEF = longitudinal ejection fraction; LGE = late gadolinium enhancement; LV = left ventricle; REF = radial ejection fraction; RV = right ventricular; SRV = systemic right ventricle; TAPSE = tricuspid annular plane systolic excursion.
