Key result
A David operation was successfully performed to treat progressive neo-aortic root dilatation and reshape the valve geometry in a 13-year-old boy with prior arterial switch operation.
Case Report (n=1)
The David operation is a feasible surgical option for treating progressive aortic regurgitation and neo-aortic root dilatation late after an arterial switch operation in pediatric patients.
May support David operation in select post-switch cases; hypothesis-generating and should not yet change practice.
A 13-year-old boy (body surface area: 1.77 m2) was born with a transposition of the great arteries. He was treated with an arterial switch operation (ASO) at the age of 11 days. He thrived for 10 years, but periodical transthoracic echocardiography depicted progression of aortic regurgitation (AR) due to bicuspid aortic valve and neo-aortic root dilatation (Video 1, left). The left ventricular dimensions at end-diastole and systole were 69 and 47 mm. The measurements derived from cardiac computed tomography suggested valve repair would be feasible (Figure 1) and David operation was performed to treat the progressive dilatation of neo-aortic root and reliably reshape the valve geometry (Video 2).

Nakaji et al. (2021) conducted a case report in Aortic regurgitation of a bicuspid aortic valve with root dilatation late after an arterial switch operation (n=1). David operation (valve repair) was evaluated on Treatment of progressive dilatation of neo-aortic root and reshaping of valve geometry. A David operation was successfully performed to treat progressive neo-aortic root dilatation and reshape the valve geometry in a 13-year-old boy with prior arterial switch operation.
