Right Ventricular Performance and Mass by Use of Cine MRI Late After Atrial Repair of Transposition of the Great Arteries

Abstract

Cine MRI allows quantitative evaluation of both RV and LV mass and function late after atrial repair of TGA. Longitudinal studies that include these measurements should prove useful in determining the mechanism of late RV failure in these patients. On the basis of these early data, inadequate hypertrophy does not appear to be the cause of late dysfunction in this patient group.
