Abstract:
Late development of annuloaortic ectasia (AAE) and progression of aortic regurgitation (AR) are widely recognized outcomes following an arterial switch operation (ASO). We treated a 29-year-old male with AAE and rapid aortic root expansion, who underwent ASO as a neonate and aortic valve replacement (AVR) as an adult. He was diagnosed as having dextro-(D-loop) transposition of the great arteries after birth and underwent ASO at the age of 13 months. At the age of 19 years, AVR was performed for progressive AR. AAE developed after AVR. In patients who have undergone neonatal ASO, AAE may occur following AVR decades later.
