   • the definition carries a high heterogeneity. Prevalence is 28% when based on a tricuspid annular peak systolic excursion <16 mm, 18% if based on a RV fractional area change <35%, and 21% for RV S'<9.5 cm/s. May occur in pressure overload, cardiomyopathies, ischemic, congenital, or valvular heart disease, arrhythmias, and sepsis. It is common in patients with heart failure with reduced ejection fraction, and it is associated with poor prognosis
