Abstract Objective: Patients with Dextro-transposition of the great arteries status post atrial
switch (dTGA s/p atrial switch) are “at-risk” for systemic right ventricular (RV) dysfunction. Due to complex RV geometry, echocardiography (Echo) does not allow
accurate determination of ejection fraction (EF), but cardiac magnetic resonance imaging (CMR) allows quantitative right ventricular assessment. Measures of ventricular
deformation may be precursors to global ventricular dysfunction. The primary aim
of this study was to characterize imaging and clinical findings for adult patients with
dTGA s/p atrial switch.
Design: This was a retrospective cohort study of patients with dTGA s/p atrial
switch operation (February 1966… More >
