Right ventricular outflow tract systolic excursion: a novel echocardiographic parameter of right ventricular function.
Right ventricular (RV) function has important prognostic and therapeutic implications. Assessment of RV function using echocardiography is challenging. The aim of this study was to evaluate a new parameter of RV function, right ventricular outflow tract systolic excursion (RVOT_SE). ⋯ RVOT_SE is a novel, simple, and promising parameter for assessing RV function, and it is associated with poor survival.

Comparative StudyComparison of right ventricular longitudinal strain imaging, tricuspid annular plane systolic excursion, and cardiac biomarkers for early diagnosis of cardiac involvement and risk stratification in primary systematic (AL) amyloidosis: a 5-year cohort study.
To determine the role of assessing right ventricular (RV) function, using standard echocardiography and Doppler myocardial imaging (DMI), in the early diagnosis of cardiac amyloidosis and in the prediction of mortality. ⋯ DMI measures of the RV can identify early impairment of cardiac function or stratify risk of death in patients with AL amyloidosis. Further studies with longer follow-up are warranted to confirm these results.
