Influence of coronary arteries transfer on the geometry of the neoaortic root in arterial switch

Zhu and colleagues1 raise an important issue and confirm that some degree of aortic valve insufficiency and aortic root enlargement is not rare after aortic switch operation (ASO).2-4 Apart from bicuspid aortic valve, all 3 other predictors of aortic root dilation in the study are caused by an initial enlargement of the pulmonary annulus in the presence of a ventricular septal defect (ie, Taussig-Bing anomaly, previous pulmonary artery banding, and left outflow tract obstruction [seen in transposition of the great arteries-ventricular septal defect-aortic arch obstruction]).
