Key result
Valve-sparing neo-aortic root replacement successfully reduced the sizes of the aortic sinus and annulus, with only mild aortic regurgitation remaining at 12 months post-surgery.
Why the study?
Does valve-sparing neo-aortic root replacement improve aortic root dilatation and regurgitation in a patient with prior arterial switch operation?
Population

Does valve-sparing neo-aortic root replacement improve aortic root dilatation and regurgitation in a patient with prior arterial switch operation?
Valve-sparing neo-aortic root replacement (David operation) can be successfully performed for neo-aortic root dilatation in adult survivors of the arterial switch operation.
Lee et al. (2023) conducted a case report in Neo-aortic root dilatation after arterial switch operation (n=1). Valve-sparing neo-aortic root replacement (David operation) was evaluated on Postoperative aortic sinus and annulus size and degree of aortic regurgitation. Valve-sparing neo-aortic root replacement successfully reduced the sizes of the aortic sinus and annulus, with only mild aortic regurgitation remaining at 12 months post-surgery.
