Abstract
Background The most common cause of a systemic right ventricle is atrial redirection surgery (Mustard repair) in the setting of complete TGA. Decreased RVEF is common and is a predictor of morbidity and mortality. Cardiac magnetic resonance (CMR) cine imaging is the reference standard for assessment of right heart size and function. However, the optimal method of RV planimetry using CMR in patients with Mustard palliation for complete TGA remains unclear.
Highlights
The most common cause of a systemic right ventricle is atrial redirection surgery (Mustard repair) in the setting of complete the great arteries (TGA)
To determine the reproducibility of axial versus short axis methods for measurement of right ventricular volumes and ejection fraction (RVEF) in adults after Mustard palliation for complete transposition of the great arteries (TGA)
Consecutive adult patients with atrial redirection surgery (Mustard procedure) for complete TGA were identified from an existing database and steady state free-precession cine images acquired on 1.5 T commercially available scanners were reviewed
