Kaplan–Meier estimates of event-free survival for 136 survivors after the arterial switch operation. Events included late death, reoperation and at least moderate neoaortic regurgitation. Taussig–Bing anomaly (TBA) group showed a lower (p < 0.001) event-free survival than the others. Simple transposition of great arteries (TGA) versus complex TGA, p = 0.763; simple TGA versus TBA, p < 0.001; complex TGA versus TBA, p = 0.001
