title: Late complications and pathological findings of the arterial switch operation.
abstract: We describe aortic root dilatation, severe aortic regurgitation, and pulmonary artery stenosis that were accidentally diagnosed 23 years after the arterial switch operation for transposition of the great arteries in situs inversus. We successfully performed the modified Bentall procedure and pulmonary artery reconstruction. The pathology of the dilated aortic root revealed intimal atherosclerosis and linear necrosis of the tunica media, suggesting the vulnerability of the pulmonary artery to systemic pressure.
