Key result
Patients with operated transposition lacked overall aortic helicity compared to healthy volunteers, and 88% of those with atrial redirection showed pulmonary trunk vortex formation.
Why the study?
Does flow-sensitive four-dimensional velocity-encoded magnetic resonance imaging reveal abnormal blood flow patterns in the aorta and pulmonary trunk of patients with operated transposition compared to healthy volunteers?

Abnormal aortic and pulmonary flows in operated transposition merit prospective study; leaves open their prognostic value.
Observational (n=37)
Does flow-sensitive four-dimensional velocity-encoded magnetic resonance imaging reveal abnormal blood flow patterns in the aorta and pulmonary trunk of patients with operated transposition compared to healthy volunteers?
4D flow MRI demonstrates that patients with operated transposition have abnormal aortic and pulmonary blood flow patterns, including absent aortic helicity, regardless of the surgical technique used.
Riesenkampff et al. (2013) conducted an observational in Transposition (n=37). Operated transposition vs. Healthy volunteers was evaluated on Systolic flow patterns in the aorta and pulmonary trunk (helical flow and vortex formation). Patients with operated transposition lacked overall aortic helicity compared to healthy volunteers, and 88% of those with atrial redirection showed pulmonary trunk vortex formation.
