Aortic-Valve Sparing Repair and Homograft and Dacron Pulmonary Reconstruction Long-term After Arterial Switch Operation.

The arterial switch operation is the gold-standard treatment for dextro-transposition of the great arteries. Long-term follow-up data are beginning to reveal its natural history and associated late complications, including various reoperations for those complications. Given the unique anatomy and the increasing longevity of these patients, there is a need for effective surgical repair options to address aneurysmal and degenerative changes in both neoaortic and pulmonic roots. Thereby, we describe our technique and the novel considerations for prosthetic choice with reconstruction of both the neoaortic root and pulmonary artery, with satisfactory postoperative results.
