Table 1 Differences in geometric variables and hemodynamic response to exercise between TGA subjects and controls. p<0.05 is considered statistically significant.

From: Abnormalities in aortic arch geometry do not lead to reduced exercise performance: a comparison study between patients with transposition of the great arteries repaired by arterial switch operation and normal controls
