Application of Classic Heart Failure Definitions of Asymptomatic and Symptomatic Ventricular Dysfunction and Heart Failure Symptoms With Preserved Ejection Fraction to Patients With Systemic Right Ventricles

Heart failure guidelines classify patients into subgroups with asymptomatic versus symptomatic ventricular dysfunction versus heart failure with a preserved ejection fraction. In this study, this approach was applied in a series of patients with complete transposition of the great arteries after atrial switch to assess to what extent this classification fits patients with systemic right ventricles. The study included stable adult patients after atrial switch, stratified according to preserved versus impaired systolic function (fractional area change ≥0.40 vs
