Submitted July 20, 2011; Accepted October 6, 2011. Neoaortic root dilatation and neoaortic valve regurgitation following the arterial switch operation for transposition of the great arteries may ultimately require neoaortic root and/or neoaortic valve surgery. The ideal surgical approach to these lesions remains debatable. Hazekamp et al, in 1997, introduced the replacement of the neoaortic root by the neopulmonary autograft and named this procedure the switch back Ross operation. We report two patients who were successfully treated at our institution with the switch back Ross operation, with good results at, respectively, four- and five-year follow-up.
