Key result
Twenty years after the arterial switch operation, clinical outcome is good and aortic valve function is preserved in most patients, although aortic root dilatation is present in 65%.

What are the long-term outcomes regarding aortic root dimensions, left ventricular function, and quality of life 20 years after arterial switch operation in patients with transposition of the great arteries?
Twenty years after arterial switch operation, clinical outcome and aortic valve function remain good, but aortic root dilatation is common, emphasizing the need for careful long-term follow-up.
Vandekerckhove et al. (2009) conducted a cohort in Transposition of the great arteries post arterial switch operation (n=39). Arterial switch operation vs. Normal controls (for quality of life) was evaluated on Size and function of aortic root and left ventricle, and quality of life. Twenty years after the arterial switch operation, clinical outcome is good and aortic valve function is preserved in most patients, although aortic root dilatation is present in 65%.
